So your argument about not buying a low horsepower car is that you got held up in traffic in your ~200hp car.

Pull into the pits if you want the space. Run with groups that don't try to cram 40 cars on a 2 mile long circuit. Realize that you're not doing w2w and focus on individual corners that need work.

You gun be real frustrated with a Miata, unless you're planning on actually racing it and live in an area with a decent Miata crowd.

But hey, I'm sure many people will disagree with this.

edit: Agreed with the above. I bought my S2000 for about $12k and it came with $$$ Penske double adjustables, $$$ Karcepts swaybars, and a bunch of other little things. I'm $20k deep in it now and it's just a pretty basic track car.
I'm one of those people. I started off in an '02 NB and it taught me more about driving than any car I've owned since. I'm also not the sort of driver that gets frustrated at other drivers for holding me up, I'll just go sit in pit lane for 30 seconds. And I definitely LOVE running down "faster" cars in "slower" ones. The singular most fun experience I've had on track was outpacing a guy in a v8 Challenger who'd been legging it down the straights all day when the rain came out and power suddenly didn't make up for his poor cornering.

^^ You'll want one already track prepped. The costs add up QUICK and don't reflect upon resale. Example:

I may have to sell my track-prepped miata soon. You'll laugh when you see how cheap it'll go for.
If you are aware of any sorted, decently track-prepped Miatas for sale for under 8K, let me know. I haven't found any on any sites I've searched; I see ones with "tired engine, needs refreshed" and "car hasn't run in three years" at 10K.

Using your figures, car safety mods + tires should cost around $5600 at max. If I do any secondhand shopping I'll come in under that. That'll keep me under the mod cost for the BMW and still make a track-only car the financially smarter move. I can wait on shocks/springs/sways - maybe during the next offseason I'll do some work in the garage; I'll have more $ then.

That's the most definitive and helpful info I've been able to find on track-prepping the 1er(thank you), and frankly, isn't that comforting.

What's your experience with over/understeer being corrected by wheels/tires, and what's your experience with clearance? From what I've been able to find, which isn't a whole lot, 18x8.5 inch wheels with ET45 up front with a 3mm spacer and 18x9.5 ET62 rears with caster/camber plates and aggressive alignment fits the largest non-extreme non-square setup, but requires rolling the fender. I was looking at the Evo Raceworks oil cooler and brake ducting for the car, but if I combine that with wheels and tires, front fender rolling, JB4 tuner and Meth injection kit, diff mounts, and possibly swapping out the diff for an LSD down the road the cost is close enough to option #2 that it almost makes no difference, financially.

Option #2 is "always the answer" - leave the 1er as a DD, buy a track-only Miata for relatively cheap, track-prep it immediately and slowly add to it over the next few years to eventually move to SM.

If you want the 135 to be a real track car you basically want to go full 1m conversion. There's a set of fenders/hood in the loft of our shop if your interested :twisted:

The fenders allow a much larger tire, which, along with a proper alignment and a 29mm+ front swaybar, go a long way towards correcting the handling issues present in a short wheelbase high-torque car. If you want an LSD, you'll need a diff cooler and tilton pump or else you'll cook the fluid in a 20 minute session.

Honestly, I could go on and on, but the best answer is option #2 or option #3 which is sell your 135 and buy a 1m. The 1m driveshaft and axles are different to accommodate the M3 diff, so a "1m conversion" is so expensive that it basically doesn't make sense which is why the hood and fenders are in the loft and not on the customer's car.

Sorry, I know I'm harping on this... I just really can't think of better bang per buck than SM for something that just works - you can run it in basically any organization, the parts support is there, it's not using any weird formula car bits, it just starts, etc. Dad and I built a T4 MX-5 (which is basically, prep-wise, the same idea applied to an NC) and it's a hoot, but if we didn't have the NC...

Mazdaracers is the defacto Spec Miata forum. I figure it's worth spectating at some wheel to wheel events, finding Spec Miata guys, making friends and trying to see if they know someone looking to get out of things... for every car that's posted on a forum or sales site, I'd wager that there's at least one more sitting in someone's garage that they're willing to sell but not quite eager yet.

It's a compromise.

You end up needing a second set of wheels because tires do noticeably fall off when you street drive them (and that poo poo is expensive when they last 5 days as-is)
You end up needing to prep / de-prep the car every event -- swapping pads and maybe rotors, depending on the compounds you're using and the fucks you give
You need to worry about being able to drive the car to work Monday
You're limited safety wise as you can't just add a roll bar, cage, or fixed back seat to a street car safely

Makes sense. I only really do the occasional track night event so I'm not all that experienced yet and feel the need for more serious setups.

I guess this is the best place to ask, but I'm looking for the best rallycross tire in near stock size (185-60-14) for my Stock-4WD class 323 GTX. I've seen the General Altimaxx Arctic mentioned as the one of the best options, really just looking for the best place to buy them. I'm in sandy (DG soil) with little actual gravel content, and would like some streetability since there's lots of well groomed dirt roads around. I'm in sunny California in the coastal mountains so they'll never see ice or snow, or likely even sub 50degF pavement.

Also, what is a decent street/track tire for a 15x6" wheel? I have 195 tires on there looking pretty square, so probably 195/55 or 205/50? They're 2002-sih Lancer OZ wheels. Last time I looked was before the UTQG 200-treadwear wars!

Firestone winterforce v1 is THE rallyx tire if you can get your hands on them. Lots of void space and the sidewall is sharp so they have good lateral dig. Can you not run gravel tires though?

Looks cheap! I haven't heard of them, is there a second version to avoid? Gravel tires as in real rally tires? I've never seen decently priced ones, and $200 a pop for Maxxis ones are a bit steep for something that likely couldn't utilize the benefits

I'll set the building on fire
At the same time, you can occasionally track your daily driver and a few things like an oil cooler, brake pads, and possibly some suspension would make that 135 more fun and more reliable without having it suck on the road. The NT01s are fine to just drive the track with as well so you don't really have to worry about getting them there and swapping wheels/tires. You can even put the pads in ahead of time.

There's a "Version 2" which has a different tread pattern and doesn't have the cuts in the sidewall. This is what you want:



All separate tread blocks and the sidewall has the sharp angles. Our regional is basically all gravel but I understand that a lot of americans use them too for mud.

One thing to note. The suspension package on the Spec Miata is what non-spec racers would call 'bad.' If you're buying a spec car so you don't have to deal with cage/harness/seat/fire system/steering wheel stuff that's great. But unless you plan on actually running in SM there are significantly better options for suspension.

SM runs 700/400 springs, the current open suspension hotness is 1000/500 as shock development has increased and there are shocks that can control those rates for the Miata now.

I actually agree with this, though note that there have been shocks that could cope with those sorts of spring rates on Miatas for as long as there's been Miatas. Similarly, 205 DOT-Rs (including SM tires) are faster on wider wheels, and the cars go faster with more power.

My view however is, "so what?"

If one is doing HPDE... last I checked there isn't an HPDE championship, so it seems to me that going down the rabbit hole of open suspension is a lot of money spent with no gain. And, this is going to expose my biases but whatever, when one stops loving around with HPDE and tries W2W, you're not stuck with either A: pulling a bunch of stuff off your car and trying to sell it, B: being a backmarker in a class with people who spent more on their open suspension and every other part of car prep than you did, or C: having 4 people in your run group.

Even if sticking to HPDE and poo poo, wouldn't it be nice to have a nice concrete benchmark for how you're doing? Not "OK, there's this guy that has sort of similar mods but more power and he's faster but this other guy with less mods is slower... uh... hm." but "OK, I'm within 5% of lap record of these guys with cars capable of the same lap times as mine within a couple percent."

But that's me, who spent most of last year wondering why I didn't beg/borrow/steal my way into a W2W ride 10 years ago. Chalk this up to arrogant dickery if you want, but at this point I literally cannot understand why someone would spend an equivalent amount of money doing track days as they would running an SM.

All excellent points. I feel largely the same way too but I have heard one good reason to stay hpde. A friend of mine does hpde and could easily afford to w2w anytime. I asked him why, he told me he was a sore loser. Track days were his vacation / hobby and he knew that if he added competition he would get pissed if he wasn't winning even if he went out and did the best driving of his life. He said it would suck the fun out and be frustrating.

Personally I would have the best time fighting tooth and nail to not be dead last so long as I was racing someone of similar skill. But I can see the other perspective.

I instead put uncomfortable and thin bottomed race seats in mine, cut off the rear seat humps and the floor pan was touching my rear end while driving.

... it's non-visible-quality sheetmetal work, that's not a heck of a lot of work. But whatever.

I can get low enough in the NC by taking the foam cover off of the Ultrashield aluminum seat so haven't bothered. If I didn't have the NC I'd definitely do the floor drop to an NA or NB.

I guess I just look at it as... the Miata, almost everything is a solved problem already, the suspension geometry is basically uncompromised, parts are cheap, and there's even manufacturer support and contingency programs, plus the most popular wheel to wheel class in the country. Unless you want to go faster than that doing W2W (which is why I'm building RX-7s, that and I actually like making solutions rather than relying on buying them) it seems like a fuckload of positive points.

Ever race seat I've seen has had replaceable cushions. I wouldn't be surprised if many models had the same shell but different sized cushions for small/medium and large/xl. Whatever seat we had in the endurance car we'd remove the bottom cushion for our tallest driver ~6.5 and put two in for me at 5.6...I also stuck an extra back cushion behind me.

Not having to share a car means I finally will have a seat that fits me. Downside is no one else will fit
