steve,
the back just isnt absorbing bumps like the front. the front absorbs the bumps (remember im driving new york pothole filled crack infested roads) and the back hits them. the lower pressure in the rear seems to help the rear soak the bumps.

this is on the street. the next autocross i can drive the camaro in is in november which is the last event until march.

here are a few pictures of the camaro the day after i picked it up, just as i picked it up, dirt and all

and here is the firebird before i dropped $1800 at paddockparts for parts to re do the interior

Cool Camaro Z28 for AX

I'm hardly a nationals threat, but I run 55 front, and 44 rear (BFG KD with 44 psi sidewall). If I run less in front I get scrub marks on the sidewalls.

I used to short shift into 2nd, but found my times improved if I stayed in 1st more -- on a tight course I can run the whole thing in 1st. I did have to learn to modulate the throttle, and not just floor it like I did on my heavy, underpowered FWD car. Also be careful downshifting to first you don't kick out the rear.

Welcome to Camaro fun! To quote a 944 driver after riding in my car, "I love the feel of that power! And it has alot of grip!"

dave
thanks for the advice. i will try the runs both ways.

having owned a 944S2 with a stock suspension except for koni yellows instead of the boge shocks and driven the camaro with all the mods for 700 miles so far i can only partially agree with your friend.

yeah the camaro has gobs and gobs of power, but the 944 had handled much better, and it also rode a lot better. maybe the mods on my camaro arent set up right so im not making a blanket statment here. just that my 89 stock 944 with 208 hp would have probably creamed my 93 modded camaro with 275+ hp in most situations.

my 944 is in an ad in grassroots motorsport magazine. its a 1/8 page ad that gets re run every month.

My car is basically stock, but I have found that I run about 42 psi up front, and 35 in the rears. The car has a lot of oversteer, but it can be carefully modulated out of turns and yield a good deal of acceleration. On tight turns I usually end up bringing the rear around a bit and it seems to reward my times.

I have never had to run a course where I had to shift to second for long, but mine certainly is hesitant (with or without rev matching) to go back into first, especially under hard braking.
I have found that my biggest worry is making sure I am off the brakes (no e brake, no foot brake... just level ground) while they are cooling to prevent warping... 26k and on the stock rotors after 20-30 events... not bad.
I also seem to burn my PS fluid after a few events, although the semi syn you can buy at any local pep boys seems to last a lot longer... and my pump has since shut up.
Oh yeah... your car is six inches narrower than you think Every camaro guy I know seems to underestimate the length, and overestimate the width.

chris, by shifting you dont find yourself upsetting the suspension balance?

I have run courses fast enough (65mph +/-) where in a quick straight shifting is by far worth the minor inconveinience. Most cars you have to run more than one gear... you can usually downshift going into a tight turn (while on the brakes, rev match and pull it back into gear ala heel toe) , and upshift coming out of one without no dire consequence (in my experience) My car isnt too keen on it, but i have run other peoples cars where shifting is a necessity (not an option) and it works nicely.
