Title: What class am I? *Thread*
Post by: RyanHallock on April 05, 2009, 07:53:40 pm
This will probably come up a few times a year, might be good to make one general thread for the questions.

My '02 ended up spinning a rod bearing, so, I'm in to a new car.

2004 Subaru RS. StopTech drilled/slotted rotors, STi rear-sway, stock STi BBS' (17x7.5), 225/45/17 Potenza RE-01Rs.

Class?

It's STX still, isn't it?

yea, as long as it is not an 06+ (2.5 liter)

He has an RS not a WRX.  All of the RS's are 2.5L, and go to STX.

RS = not turbo correct?  ST (former STS ) allows NA up to 3.1.  There are a bunch of rules related to brakes: voids for slots/holds < 10%, and for ST must be same rotor material as stock.  STX/STU brake rules allow more.

I am just making the assumption that the RS comes with an LSD in the rear, which would kick it out of ST, right?

looks like the 2.5 rs only came with a rear lsd in 2000-2001and possibly in 99.  Even then I think its a viscous coupling which is allowed in ST.

The only thing to worry about are the brake rotors but I doubt you really have to.  That rule was made to stop people from dramatically lightening their rotors.

14.6 BRAKES
A. Cross drilled and/or slotted brake rotors may be fitted (same
size/type/material as standard) provided all such voids are within
the disc area, and comprise no more than 10% of that area.

You should be fine for ST with your mods.

I ran STS/STX with my '02, and was pretty sure it'd be the same. Only question I had was with the brakes.

wow thanks for the speedy reply. i was looking through the general rules and such but i couldent figure out what ESP was. im just curious what places me in that catigory.

E Street Prepared

Mostly, it's the tune.  I'm assuming the protune you have modifies the boost from stock level, and that puts you here.  If you kept a cat somewhere in your exhaust, and put the boost back to stock, then you might be eligible for STX.

i do have one high flow cat in the down pipe and it is a 2.0L not the 2.5L, but my boost is turned up so that would place me in ESP?

Correct.

I'm trying to get the class for my car, but not liking what the rule book is telling me. I have a 2001 BMW Z3 Coupe (3.0L, NA). Only mods currently are  performance intake, and wheels/tires. The OEM tire sizes look like 225 front, 245 rear. Right now I have 235 front, 255 rear. As near as i can tell, this puts me in STX. Any chance I'm wrong? If I had 225/245 tires, would I fit into ST for OEM sized tires, or does the 225 limit in ST override that?

So, looking through the rulebook, you are not eligible for STS based on your displacement.  Now, from there, I'm not sure if you are eligible for STU or not (anyone else want to chime in?).  That being said, you are eligible for B Street Prepared, and you could run the Road Tire class with a BSP index.

Z3 is a two seater, so automatically not in ST or STX. Good chance it is eligible for STS (formerly STS2). For these classes, tire size is not regulated, but wheel size is, I think STS has the same max width that ST has -- 7.5in. So, check the STS listing, if your car is eligible (maybe, maybe not) and your wheels are 7.5 inches wide (or less), then you would fit into STS. If you're not listed, then Jim is right, BSP. Although, if you took off the intake you would be able to go back to stock class (BS).

Rulebook says STS is limited to 1.9L NA, so that dq's him for it.

BSP it is. Thanks for the help!
