Default Article on K-Pax building the Volvo C30 World Challenge race car

Found these articles while looking for info on JRZ dampers. The K-Pax shop built the championship winning AWD Volvo that let Randy Pobst win a championship in. Here they build a pair of cars for the new touring car series. Some good info:

Hmmmmm...maybe they're just trying to throw the incognoscenti off the trail...

Great shots. But unlike those high end racing cars in the upper series that corner flat, these guys in the bottom series can hardly modify the suspension. They and all the Civics in that class were lifting, as were the VW's. But PD in GTS was not. Wonder what he knows. Maybe he's been reading RCE for a few years.

Since I cannot afford to re-engineer my Type R's rear suspension, I guess I will just keep on lifting (about 1" I'm told by the guy driving the Dasio who was chasing me for a long time, till I um, let him by). Maybe I need me some stiffer front springs. Just went to the dyno for a tune on my new S300 Hondata for the new forged pistons and rods setup. 293 WHP and 210 ft-lbs at 10.0 lbs of boost and 11.7 AFR. Could add a little more boost with a new MAP sensor. Might cause even a little more lift. Maybe I need a plate diff as described in those C30 articles.

Ah, I didn't realize it was basically showroom stock. Those Poor Guys! All they've got to work with is shocks and springs and barz - you can hardly paint a portrait with such a limited pallet. BUT, if they could "re-engineer" their suspension, then they could keep that inside rear down, and pick up like 3 or 4 seconds per lap just like that AND eliminate those hairy scarey moments when the inside rear instananeously lifts and all the crucial geometric intersexions go every which whizz way and the transient inputs to the drivers gluteus data processing center become chaotic and incomprehensible and the understeer increases hyperbolically and PD simply drives around you in the marbles on the outside line by virtue of all that extra gripz he's getting out of that well and firmly planted inside rear.

Claude - you should definitely stiffen the front of your kaa, and keep stiffening it, and keep going faster, and faster, and faster, until you just can't go any faster...well, without giving it any more boost anyway.

Scott, who just doesn't understand how or why people started going rear stiff with front wheel drive kaas in the first place...it shakes my faith in human individual and collective intelligence...yes it does indeed...

Ok, I hope I don't seem too antagonistic, obstinate, set in my ways, unthinkingly dogmatic, etc...so let me turn it into a question:

What about a "re-engineered" rear-steering rear suspension reduces our need to keep as much vertical load as possible on the inside front? Assuming of course that this years magic diff doesn't obviate the generally accepted laws of physics.

Scott, who has done experiments with forklifts...they were inconclusive...and scarey...
