Even if you gain a couple of pounds per corner, it would be worth it IMHO if you're putting a lot more power down.

RFP1's in 17x8 are about 4lbs lighter per wheel than stock, and won't break the bank either.

Yeah, that was one of the wheels I had in mind when I wrote that post. I've had three sets of RPF1s on various cars over the years, and I'm thinking about picking up another set for my BRZ.

Springs & dampers, and bushings tuned to prevent wheel hop can have a large effect on how much power you can put down. Tire compound and construction will have more effect then size.

OZ Allegrita's are also very light, but they're about $500/set more and I don't like them *that* much more.

- Stickier tires
- wider tires
- stiffer rear subframe bushings
- stiffer differential bushings
- slight change in ride height to change weight distribution to rear
- increase squat under acceleration (maybe softer rear springs or stiffer front springs, or maybe not since understeer will increase)
- will sway bars have any effect on this?
- traction bars?
- alignment? maybe less camber on rear tires?(though it might loose some cornering speed)
- will stiffer engine mounts help?
- will stiffer transmisison mounts help?

One thing I noticed is missing from your list: big, goofy spoiler. :D

How fast would a formula 1 car trap? I'm sure you can figure out my point :thumbsup:

Alright man I understand your points, and they are completely valid. I also understand that people have different wants out their cars. The s2000 wasn't made for drag, but does amazing. This car will be used for mostly circuit, road course racing, not drag, but it cant be denied that its already proved to be a valid platform in that field.

We will all use this car for different reasons, and if it works it works :w00t: If we all did the same thing with our cars, it would get boring real quick.

Nitto NT555's are really sticky and should cost about 165 a piece, very affordable and will last a decent amount. I haven't broken mine loose yet and it corners even more amazingly. I've got way more cornering confidence, which you don't seem too worried about, but thought it was worth mentioning.

I've also got the Cusco powerbracing and that really stiffened the chassis up. Also look into whitelines bushings, specifically the tranny mount bushing. Takes some slop out of the tranny under acceleration which translates to better power delivery.

I completely agree and I will go to the drag strip at some point (just for fun). It's funny you mention S2000, because thats the car I just sold to get the FR-S :)

Haha nice, they are both great cars. Let us know how you do.
