I have to assume everyone is talking about national events, so what about the stock street tire class? I think it would be competitive, especially if its wet at all.

To be honest, I think it'd be a blast in RTA with the GS pax. Put a big rear bar on it (and make sure you get one of the 2000-2001 models with the viscous rear diff), set of koni yellows for some shock stiffening and some 225/45/16's. Done. Fun DD and fun RTA setup. Wouldn't even really need to be raining IMO.

I've got an 01 with 160,000 miles. I'm willing to bet the rear diff isn't so viscous anymore. :P

In my opinon, no, but if you spend a lot of money in Street Mod it could be awesome.

Why not post our last autoX results from the other week? You were insane. It was so awesome watching you mop the floor with most of us last event. Just a proper set up and stock power and you made so many drivers look like they had serious learning to do.

Made my first meet in this car something to remember.

At nationals, I still think it is competitive in DSP if you are just trying to trophy. For overall win...you will need to get extremely lucky. However, you will have to have the car almost fully modded to the rules to fight for trophies.

At Pro solo's, the chances of winning are even better. Usually the BMW's are putting down 2.2 60ft times while I was getting 1.6 60 ft times. But, make sure you have some extra transmissions handy.

To bring this thread back from the dead, I have a 2.5 RS with nothing more than a rear bar and some ventus evo's in RTA and it's a blast. Unlike most of the members on NASIOC i havn't owned or driven anything for a long period of time over 300 WHP so I may be a little bias on the fun factor but at the local level, a set of direzza's, AGX's, a set of camber bolts, auto x alignment and a bigger rear sway will be alot of fun and keep you competative in RTA. This also makes for a comfortable ride home after the event, doesn't rape your wallet and requires very little work to go from event ready back to DD or visa versa.

National level, IMO:

GS
This could be interesting, though I drove a stock one the other day in an autocross and I forgot how horribly slow they are. Rear sway bar, RT with PAX... could be interesting.

STC
Too heavy. Good luck with that.

DSP
Nope.. too much development for those BMWs. Knife to a gun fight etc. (Also, now with a rule change it's not the RS that is the best car, it's the L with an RS drivetrain if anything.)

SM
Again, considering the RS is the chassis because drivetrain is open - Nope.
L Chassis? Perhaps but the 2.5 engine hurts when it comes to weight.

2.5 RS N/A - 2550lbs
2.5 turbo - 2,850lbs

Compared to an Evo: 2,640

Maybe somewhere in there is a 2-liter swap into an L Chassis, get it below the 2,640 and ballast up to help with handling, but that's not a 2.5 RS anymore by a long shot.


Prepared, Modified, etc: No benefit to a 2.5 RS shell as a start in those classes.. you're better off selling a 2.5 RS to a Subaru enthusiast and using the $ to put into an L shell.


I am going to enjoy mine going back to nearly stock as a daily/trip light track duty car.

Just some quick clarification, an AWD 2.5 car in SM would need to weigh 2,970 while a 2.0 AWD car would need to weigh 2,820. Minus 200 lbs if you went to a 275 or less tire and it would be 2,770 and 2,620 respectively.

If you convert to RWD then it's a few hundred less again due to the weight*displacement calculations.

Honestly, with the turbo 2.5 you can do an RS without issue in SM and be very good locally. It just takes a lot of work to do it nationally. And if you had a choice of shells to start with, an L is a better starting point due to the lower weight.

Agreed with Jon. GS or RTA are probably the best shot it has at being nationally competitive.

If you just want to have fun, I enjoyed mine in STC trim. The suspension work got it to handle decently, but it was still streetable and I didn't have to change wheels at each event.

Right. But honestly, anything can be made to be competitive locally. (Provided you don't have one of the 5-10 of the top cars in class local to you, and you don't have a pro class for them to run in.)

Right, which is why other than maybe GS or RTA/GS, there is no place for the 2.5 RS in national level autocross anymore.

Breakage happens in every class above stock....or you end up staying painfully slow. The nice thing about prepared is the leeway to overbuild for reliability.

Alright, I've been running a Prepared Cooper S for 3 years. Now I'm in this thread cause I want to run RTA.

I bought completely stock 2000 rs25 coupe with a fresh engine, and extra oem wheels. RTA/GS will be fun ..I'm looking for some setup advice.

As far as running prepared yes its fun but... dedicate a car to only autocross $$$. re-engineer everything to work around 11" wide bias ply tires $$$. Build most things yourself they don't make bolt-ons for prepared. I spent about 200-400hours a year on development. Drive 3 or 4 minutes at an event. learn to drive much faster. My best points so far 935 against national champs. It's been fun. I'll still be doing it.

But I just want to have some fun in a car that I believe is likely to be competitive in RTA(GS PAX)

^^^At the risk of sounding like a penis....I'd say you were just doing it wrong in prepared.

That may only be because the re-engineering, development, and building aspect is part of the fun (for me). I agree 100% about the low seat time and dedication to one dicipline. I am now beginning to broaden my horizons with changes to allow the car to be used in other venues, such as hill climbs and track duty with a known autocross setup to fall back on when it goes to big events.

I have very limited experiance with Solo but I really enjoy running the RS in RTA. From what I've seen the newer WRX's are the car to have in this class these days but I'm not sure if any one has tried to make a 10/10th's RT RS yet, so who knows. I've done fairly well locally against several WRX's and with nothing more than some Hankook Ventus v12's, adjustable RSB and an air filter. Due to stock rule set and limited camber, toe and caster adjustments there's not a whole lot to the setup of the car that is legal (that I am aware of). Will be interesting to see how far some one who has alot of seat / development time can take an RS...

I'm running in GS.

We have 3 stock RS in GS!

Everyone complains that the RS hits third too often. I figured go ahead and embrace it with shorter tires-- I'm running 215/40/16 v710 there 2" shorter than stock. I give up a little width that I could have in the 245 710, but I gain a lot in gearing, less weight, and the sidewall is square with the wheel so a higher sidewall spring rate, oh and the car is 1" lower. right now 710's are a set of 8year old 1/16" tread test-do-they-fit how's-the-car-like-em's. Will get a new set for March30 Series Kick-off.

There is an a6 in the same height, but Its easier to get the suspension all sorted with the 710's feedback.

I've installed rear AGXs;set at #6 with 36PSI, where I can throttle rotate and cautiously trail-brake.

waiting on some bits for the fronts. My front left strut only has oil on the outside, it claps. the front bobs 4x when you press it down. 41-42 PSI is stable in the front. surprised how well the front tires do on the stock alignment McStrut curve.

I'm looking at 24mm front bar & endlinks. get some weight transferred to the rear, and make those tires do a little more....

Does anyone have advice on which whiteline fits the NA header. I haevn't looked at it yet lifted, only from the side, but If the bracket bush is offset closer to the subframe the striaghter, and therefore stiffer turbo FSB might clear above the header.

Any word on group n mounts being legal for GS Impreza rs. I heard rumors but I can't find any supporting docs.

race pads go on when the chance of snow stops. then some other bits.

Despite dead strut today's non-points event 918Pts.

4 wheel drift for the first time in this car today-- nice neutral controlled feeling -- hmm how to rotate---throttle-- worked very well.

I'll be running GS with this for our local series, 950 points on pax is my goal.

(locally 1000pts = Dorsey [Last year's pro & nats EP champ], Mark Smith [DSP VW Champ] or Thorne STR)

If I do well locally with the RS you will likely see me in it in GS at Nats.

The whiteline GC turbo swaybars foul on the stock header. They are supposed to fit with the borla header, but my 22mm whiteline turbo swaybar hit my ebay borla knockoffs.

one had V8 jdm sti swap and hybrid 2L/2.5L wrx/sti swap engine.

both are much lighter than any 04+ sti.
Every time I've seen an RS swap that carried the 6 speed over, it wasn't much lighter than a GD. Are these cars still running 5speeds?

Mine is under 2800 lbs right now with factory front seats and heavy brakes/wheels. It's entirely possible to get a swapped GC (ej257/6speed/brembos/r180) into the mid 2600 range in SM.

I was initially thinking of RTA, but everything I looked at said the WRX's were killing it. GS Trophies have had pretty low pax points at nats since they Cooper S got bumped out. I think they started around 9300 and 1st was in the 9500. Much easier class to exploit than RTA.

The other big thing is tire height. NA engine need lowest gearing to launch faster. shorter tires take less angular force to rotate, as the tread weight is closer in. shorter tires lower the car for better handling. shortest sidewalls usually have the most feet back and highest spring rate. There's not much in the stock springs, and with deflection in the rubber bushes. I want things as stiff as I can get them.

Hoosier and Kumho both have short 22.6" 215's for GS.

the only shortish ST tire for the 16x7 is the Kumho XS, it behaves but is not considered a responsible tire.

When I was tire shopping, I found 200 tread wear 255/30/16 Kumho's of BFGs with a v-block pattern, but only a pair and old-stock and discontinued. the new Kumho v720s might come in some short sizes--the only size info I've found is a picture of a 255/40/17 in Tokyo. But they should be official in a couple of months. But with the WRX there RTA is not going to be the place for an RS.

I don't know if I'll build a 10/10ths GS RS. Coming from prepared I've got a solid list of my legal GS build, and I'm putting together some site/course condition paddock changeable suspension options.
