[s-cars] UrS teardown question

[Taka Mizutani]

Lee-
In STX, you're down 57hp on the WRX and 100hp on the Evo- boost mods are not
allowed.

You can't run R compound tires in STX, so I hope you didn't just make a very
expensive mistake.

Best tires for STX would be Falken RT-615, Bridgestone RE-01R- the Hankook
Z212 RS2, BFG KD and Kumho MX are further behind.

I'd think you need at least H&R race coilovers and big sway bars to get that
A4 in shape. With enough drop, you can get a fair bit of camber.

I don't know where you got those weight numbers- B5 A4s are a wash with WRXs
and Evos- they weigh nearly the same, all about 3250-3300lbs.

Evo school is generally regarded as a very good way to get a good start in
autox w/o picking up a ton of bad habits. You might have to wait until next
year to go to a school up in your area- season is pretty much over now,
isn't it?
