Specs on subframes?

...You can have a killer car but if the driver can't handle it...likewise a poor tire...

Hey, that sounds like me!!
A set of $84 18" tires didn't work so well either!

Looks like I'll be heading down to San Bernadino in March for B'ville tech inspector meeting, and Speed Ventures will be at Buttonwillow on March 11th. Maybe I need to set the idea of 18x10s aside for a while and get a set of 255/45R18 Yokohama AVS Sport....

Good point on torsional stiffness, but I feel some people may be better off buying a subframe w/ better suspension geometry unless they know how to alter it. It's easier to tie the frame to firewall, add some tubings here and there to improve chassis rigidity.



Great story on the 69 Camaro leading a bunch of GT1 cars! I love it!!

Thanks for chiming in, David. If you can come out to the SoCal track event I'll be attending this year, you're more than welcomed to drive my car. I know it's a totally different platform, but you may be able to tell some differences in behaviors between leaf and 3-link.

DP, Great post. I've seen the vintage race out at the Tustin Marine base and the first gen. Camaro's were pretty damm fast.

Yes, you're totally right that for fair comparisons, all cars have to be well developed.

The way I look at those testings are a bit different. I think any legitimate suspension manufacturer need to be able to provide baseline setting that are close enough to ideal setting to their customers, via calculations and/or extensive testing. Subtle/small things like sta bar arm length, shock valving, tire pressure, etc, are still up to customers preference, but I have a doubt that minor under/oversteer would result in huge differnce like 0.10G in skid pad performance (for a given tire, of course).

Many of today's best street tires are capable of near 1.0G traction on a well-developed car weighing in 3000~3500 lb range, so if some car put down some miserable performance with those nice tires, personally I'd be skeptical of the engineering behind the products used on the said vehicle (ie, manufacturer was unable to provide baseline settings).

I agree that the testing results won't tell you the whole story, but they at least give me rough ideas
