I don't think it has to be that drastically different. I don't recall that coilover retrofit kits for C6s require much hardpoint modification, if any.

...and I kind of don't really want to be sitting in a Corvette with a retrofit kit under any sort of hard driving. The whole point of the transverse leaf springs is to have the weight of the car be transmitted from wheels, to springs, to the center backbone. The body of the car was never meant to be load bearing in that way. That would be akin to taking a leaf spring truck and modifying it with coil springs that just sit straight on the bottom of the bed since there are no shock towers.

EDIT: I mean I don't know anything about Corvettes but that still sounds sketchy as gently caress.

I don't know how strong the upper mount points are, but the Corvette already has shocks, not... nothing. Callaway's kit specifically avoids putting full force through those points:

Maybe I've misunderstood what these kits actually do. It says in the article that the Callaway kit actually leaves the leaf springs in place and just add coils on top?

Correct me if I'm wrong since you're an engineer and all but shocks and springs are not the same thing in terms of energy. The shocks only need to dampen the compression and rebound, the springs are actually where all of the weight/energy gets transferred and stored and thus a spring mount is going to need much more reinforcement than a damper.

As much as we all love horsepower, I think this power race is getting out of hand. 550+hp is insane for a regular person off of the street to be able to handle. Do these vehicles require some high performance driving classes prior to purchase or can anyone just with enough cash just wrap one around a tree?
When the Lotus Carlton was available, each car included a performance driving traing course in the price. It wasn't compulsory, but given that they were selling something with no electronic aids and performance that was on a par with (if not slightly exceeding) contemporary supercars, someone clearly had a moment of common sense.

I believe that the shocks transmit higher peak loads to the chassis than the springs. The shocks take care of all the high-velocity, high energy suspension movement while the springs only deal with the low velocity, low frequency motion that was not counteracted by the shocks. It is the high amplitude, high frequency loads that are most likely to cause metal fatigue and thus they are the most important factor for the integrity of the chassis.

Most serious track and race corvettes run coilovers without any special mods to the mounting points. The C6R is also far from a tube frame car and uses a regular c6 chassis.

Man, I forgot how long ago it was that the Grand Cherokee (presumably that's what you mean) came out. I think it's all right though since they did pretty much update everything else and the exterior of the GC was pretty nice to begin with. If anything the new headlights are a step back.

No, I mean the new Jeep Cherokee. It was reported in the papers that the weird bulbous design is because it's taken off another Fiat family car and that this was done to save money and development time.

Oh what planet is selling a 550 hp 5.0 v8 and a supercharged 662 hp v8 (with assurances the next gen will have incrementally more power) chasing economy over power? Also, they're called ecoboost, but it's pretty clear that Ford's new round of turbo engines has power as a top priority.

And on the flip side of that, the base Corvette has 460hp and can get 30mpg on the highway.

This was the response by Jeep's head designer, Mark Allen, to that WSJ report: "It's absolutely false. It was done completely in Detroit, 100 percent." He would've probably given the same answer if that were true, but I think we can take the man at his word. Fortunately, the styling appears to have had no affect on the Cherokee's desirability, as Chrysler's best November in decades is due to this strange looking vehicle. I personally like the Trailhawk trim in dark colors.

The new 200 should be a home run.

There was an ad for the new Cherokee on right after I read this, and honestly, it's not as horrible as it was when I first saw it. I wouldn't say it's growing on me as much as I'm just getting used to it. Compared to the RAV4 or CR-V, it's definitely more interesting.

Nope, definitely not a tube framed car in the slightest. Even when they were racing in GT1 there were limits on where you could move the suspension mount points; that's much more restricted in GTE.

quote:

Type and method of operation

It is permitted to modify the position of the suspension
mounting points within the limit of 20 mm around the centre
of each original pick-up point.

Springs, shock absorbers, anti-roll bars are free as well as
the position of the centres of their joints.

Leal [they mean leaf] spring blades can be substituted by helicoidal springs.

The hub carriers can be changed but the number of link
joints must be kept.

Adjustment of the springs, shock absorbers and roll bars
from inside the cockpit is not permitted.

If the car is fitted with a suspension "inboard", the original
rocker and shock absorber axle joints on the chassis must
be maintained.

No electrical, hydraulic or pneumatic connexion is permitted
between the shock absorbers.

Not to Auspol this but I'm not sure what you guys think anyone in Aussie government could do about this. They could try to bribe the carcos to stay, which would cost Aussies a fortune. They could crank up tariffs, which would raise the price of all cars, and cost Aussies a fortune (and risk retribution). They could try some half-assed measures to reduce the (labor, environmental) costs of building cars in Aus, which would piss off tons of people and probably still not work.

This has been coming for, what, years? Decades?

There usually aren't too many interesting cars coming out of Chinese companies, but recently it seems that Great Wall will be launching a range topping version of their Haval H8.




Unibody construction with double wishbone suspension.




The regular model with a 2.0 turbo 4 and a 6AT sells locally for about the same price as a Chinese built CR-V or RAV4. It is a larger (about the size of a Highlander), better equipped vehicle with more power so that's about right for a car from one of the better Chinese marques. Styling is a bit derivative as you might expect but fairly inoffensive. I can certainly think of plenty of uglier vehicles from developed country marques.

The interesting thing is that they are going to be putting in a 3.0l twin turbo inline 6 engine with about 320hp, developed in-house. It will sit in front of a ZF 8 speed auto. I took some photos of a cutaway of this engine from the Beijing auto show last year.




Now supposing they can keep the pricing around the same or even slightly above a CR-V/RAV4? That really doesn't sound half bad.
