i think it will handle ok. the weight is much more centered than stock but the rear suspension will be its biggest down fall as far as handling goes. vertical coil overs and solid axle arent great for handling. but getting a 2700lb car with over 800hp to hook in a 1/4 isnt easy with irs and irs was much more expensive. if it doesnt run like i want in a 1/4 then i will switch to irs but for now i like it. the rear tires being 275 isnt bad for handling, a vettes are wider than that.

Okay. Yeah, I figured with a build like this, getting it to hook in the 1/4 is most important. After you get that sorted out you could attempt to get it to handle, also, but it won't likely be able to do both very well without at least changing wheels/tires. Big rears aren't always bad for handling, but I have a hunch that with this setup, you'll want the fronts to match the rears, or at least come close to it.

FWIW I think Mustangs run the same size all around for autocross, and Z06's run something like 295 rear 275 front

It doesn't matter which wheels are driven if you're off throttle. I am assuming natural understeer, when not driving wheels, because they are much bigger and will have much more grip than the fronts. Yes, if he applies power he'll oversteer... but if he has to apply throttle to reduce understeer at every turn, then the car will be very annoying to drive. The ideal setup to have in a RWD car, in my opinion, is a very neutral handling car (all four tires lose grip at the same time) if you're off throttle. Then you can gently add throttle to keep a very slight oversteer going, without getting out of control. This lets you adjust the car's attitude quite accurately through the corner, and lets you get back on the throttle earlier and more confidently than in a car with natural understeer and a tendency to snap oversteer without much warning.

He might be able to help balance things out by adding negative camber in the front, or by having a spare set of rear wheels that are closer in size or something. It is really hard to guess about that sort of thing since I don't have much experience with RWD, let alone the nuances introduced by a one-off RWD conversion like this.

^^^^ All I heard was, "Blah blah blah, Paul Walker told me negative camber is better..."

SVT size brakes? Pfff, don't insult me. MS3 brakes are even bigger. Feels like droppin an anchor out back when you put some pressure on the pedal.

yeah im still doing research. im trying to figure out what mazda's brakes i need to use... am i correct in this..

mazda3 2.0 is 10.9
mazda3 2.3/2.5 is 11.8 (same as svtf)
and mazdaspeed3 12.6?

i posted in the mazda3 forum but they wont respond.

you think those mazdaspeed brakes are good you should drive my sti with the 13" 4 pistons brembo's... i wish i could afford to put those on the focus.

Meh, it's enough braking for the car's power. No 600whp here, haha.

That brake size sounds right, though.

ok. i got a set of svt calipers that i am going to be using so i just need a 5 lug rotor that is the same as the svt. which is 11.8.

i cant afford the mazdaspeed set up or i would go that route. but for 500 i would rather save another 500 and put some brembo's on it.
