Question Auto-x Help....

Hello everyone.

I was out at the last auto-x in my OBS and got 18th in the STS class am i stupid to try and compete against all the other cars in the STS in my OBS the SCCA Solo rules say not many engine mods can be made to race in that class.

What can i do to make my car more competitive?

it was my first time ever driving auto-x or any car racing and i cut 9 secounds off my time in 4 runs. Every time i came off the corse i know i could have go faster.

Whould some R rated slicks help my time out and are they allowed in STS?

all the auto-x guys that know what there doing help me out.

Erik s.

If not see you at the meet on sunday...

Well, as far as modifications in STS, I think they would go something like this (in order from most bang/buck to least):
-Tires- R rated tires are not allowed in sts (but they are in STR), but good summer tires like the Falken Azenis, RE-730, SO3-PP, and the like are probably good for a couple seconds over a all season tire (especially the RE-92)
-Suspension- I drove a car with DMS coilovers Sunday (~$1500-$1800) and it made a big difference. Other strut/spring combos can be cheaper, but not as adjustable.
-Cat back exhaust and cold air intake

Having said all of that, the biggest difference will always be the driver. I was co-driving the same car that Mark was, and he was about 1.5 seconds faster. My times have gotten much faster and more consistent than when I started autocrossing a year ago, but I still need all of the practice and instruction that I can get. Autocrossing helps, and I could sure use an autocross school (especially if its free, or cheap ). If you haven't already, I recommend signing up to the email lists at www.rmsolo.org just to listen to the fast people, and see if they announce any autocross schools/events/shindigs coming up.

Eric,
The cheapest and most productive way to get faster is to leave your car alone and work on your driving. You say this was your 1st autox. Well, you've got a lot to learn and I don't mean that in a rude sense. What I'm saying is that you can go quite a bit faster with more experience not more mods. Me or any other driver with a few years under his belt could hop in your car and go probably 3-4 seconds quicker than you right now. Nobody was really fast at their 1st autox. It takes time and pratice. So don't be so down on yourself. Realize this is all new to you and let me stress, being a good driver on the road does not mean you'll be a good driver at an autox. They are two totaly different animals. Got up to anybody at one of our autox and ask questions, we'll be more than happy to answer them. Ask to ride along or have one of us ride with you. You'll be amazed at what you can pick up just by watching.

Before I get into what mods would help you down the road, lets concentrate on what you can do with what you've got. These recommendations are based on my experiences.

1. Tires. If you still have the RE92s you need to run about 46-48 up front and 37-38 in the rear. (tires to get are Falken Azenis, Bridgestone S-02 PPs, or Kumho 712s in that order)
2. Alignment. Makes a world of difference. Max equal negative camber front and rear, 1/8" total toe front and rear. Mind you this amount of toe will make your car squirrely at highway speeds. Something to consider. And these specs are assuming you have a stock setup. An easy and cheap upgrade is someones stock RS setup.
3. If you have your stock intake, leave it. It may not look cool but it puts out more bottom end torque than any aftermarket one. And bottom end is what you need at autoxs.
4. Seating position. You want your seat back as verticle as possible. Seated you should have your arms bent at 90 degrees whilst holding the wheel. I sit a little closer than that!
5. Look ahead. Don't be looking at the gate you're going through, look at the next one. If you think you hit a cone, do not look back to see if you did. That'll screw you up for the remainder. Better still, turn all your mirrors away so you can't see behind you. And if you do screw up, don't get mad at yourself. Forget about it and concetrate on your next run.

Way down the road and I mean way down the road, after you are comfortable with your car, then you should think about mods. And I don't mean clear marker lights! Race rubber is not legal in STS. Aftermarket intakes are. Front and rear strut bars are legal. Coilovers are legal (I would recommend DMS 40s). headers, cat back exhaust, lightend pulleys, short shifter, a decent reclining race seat. And so on. The best source for whats legal in STS is the SCCA Solo handbook. Or as you did earlier, ask here.

Sorry to prattle on so. Like I said, if you have any questions, ask away. And there are plenty of people with way more experience than me that could help. Remember, these are suggestions. You obviously can do what you want.

Good luck, Mark

Exclamation Warning: shameless plug below!

Not to detract from what these guys said (because everything said was right on), but a wise man once told me..."set you're car up the way you want it, then leave it alone and learn how to drive." So, if you're looking to do a little to the car in the short term, do it before the season gets going, then concentrate on driving with what you've got.
So now for the shameless plug: I've got a set of DMS Golds and mounts that are for sale, ($1500 for the set with front camber plates, and rear STi mounts). I'm removing all the go fast goodies from my car to concentrate on the new toy. So if you're looking for suspension (and an entire turbo conversion for that matter), shoot me an email [email protected] See you on the 6th at the next one

Eric,
I'm curious, did you read this? Did it make any sense to you? Or did it not answer the questions you asked?

The suggestions here are pretty on track. I want to stress what they said baout tires and suspension.

Handling is the most important issue after getting experience, not power. The suggestion for tires is straight up, but I would put Bridgestone RE730 as #3 on the list, and having driven on all but the Falken I would say the Yokahama A520 are not as good as the RE730 but are better than the Kumho 712's, bumping the Kumho back to #5 choice.

Thumbs up

I did read this yes....

Thank you so much for all your help i have been really busy with finals to be worrying about car stuff.

I think i'm leaning more towards the rally-x searies for next year and maybe go for auto-x when i get more time and money becouse there are only 6 rally-x and alot more auto-x's so i will be at them but wont be able to drop mad cash into another set of wheels and tires at this time so my yokahama avid h4's may have to do it for this year of auto-x
