Nice! Corners pretty flat at speed?

The 12's in back don't hurt either.

What do you mean, the 12s?

Unfortunately, the Newton book on C4 projects lacks on some technical stuff and the article on FX3 chips is an example. The article implies that Bilstein can supply chips for FX3 which change the shocks' damping. In reality, all the chip does is control the speeds at which the system changes the bypass valve setting. Unless you're drag racing or road racing, I'd leave the SRC calibration alone. You're better off having the shocks rebuilt and revalved.

The Moracca-valved SRC shock absorbers completely eliminate the "floaty" feel of the car when the SRC is in "tour" and the ride movements are low-frequency. The practical result in that, is the car's tendency towards drop-throttle or trail-throttle oversteer is greatly reduced.

For more info on the work Bilstein can do to the shocks, call Bilstein, 800-537-1085, and ask for Lou Laurenzana.

Hib...I understood that and got the message from the article that the changes would be speed setting modifications from the article but if my shocks need anything the revalve is the way I will go. Thanks for the input. For me, getting starting knowledge the book was fine to present a starting point. It was just a good beginning article for me and I'd do more research before doing anything if and when I did. The article quoted above is excellent and very detailed. Some pretty competent people own and work on these cars it seems to me. Right now mine are fine and I tend to keep it in sport or race. Overall for my use I agree, it is fine as is.

He's running a 12" wide wheel in the rear with I beleive a 345 tire.

Got it!

Ricky,
I know it's done all the time for traction off the line with powerful engines but what impact is there when front tires are one width and rear tires another dramatically wider width when cornering rapidly carving up turns with the car? Shocks and suspension control lean on the body and keeping the tires flat to the surface but tires control traction in that sense.

Having more grip behind you with engine weight up front than you do up front does what in those circumstances?

My 76 has 255's front and rear and the Z of course comes with different front to rear by about 50 mm's then the 12's make it another 10 mm's in addition. That's getting to be a big difference and I'm wondering what the effect is in road handling.

More accurately, the tires are 325 x 19 on the Z06 wheel
