Good point. I'll bring this issue up when discussing the modification with one of the local shops. I'm hopeful that I can find someone that has done a few of these already and can recommend a starting setup. Thanks for the point of view.Quote:

I was replying to someone else. And in his post, he was saying that I might not want to do the springs now because I might get the right springs without more experience. This thread does not contain any of those things. But I got your point.Quote:

That might be good for learning car control, but there's no way he'd be competitive with the stock R gear ratio.Quote:

Just change the final drive in the rear end. Everybody enjoys a good rear end service job.Quote:

Their approach was to upgrade the tires first:

Then add coilovers second:

Some interesting comments from that article:

It’s a question racers often ask: How much faster are proper competition tires than regular street tires? One second? Two? Three or more?
Thinking back to our first competitive outing with the bone-stock car at the Dixie Tour, we were easily 4-plus seconds off the pace of the prepped cars on proper tires and wheels. We had a lot of ground to make up.
Recently we ran some baseline laps with the OE 205/45R17Bridgestone Potenza RE050A wheel-and-tire package. Then, after doing nothing else to the car but bolting on the 255/40R17 Dunlop Direzza Sport Z1 Star Spec tires wrapped around 17x9TRMotorsports C3 wheels, we were well over 2 seconds faster on a 55-second course.

Using their out-of-the-box settings, we ran laps on the Tire Rack test track with the OE Bridgestone tires as well as the Dunlop Z1 Star Specs. Not surprisingly, our lap times on both tires were faster than when we drove with the OE suspension. We were a bit faster on the Dunlops, which is good news: We keep closing the gap to the front-running cars. Subjectively, the car now feels livelier and responds quickly to driver inputs.
Find the fastest guy's out there with cars like yours and copy them as your budget allows. That was my plan. Now, the limiting factor is certainly not the car, it's clearly the driver. Evo school is very good, I need to do it again, and again, and again.
Deets on the Evo school?

Salina, KS was the closest beginner class available last year. OK site, old concrete runway. Good grip, a little narrow.
Wow, those classes are really affordable:Quote:

Is their program licensed like the Skip Barber school? I've heard discussion of some sort of licensing you can get from Skip Barber that many of the local tracks recognize. But at $3000 plus airfare ... that's hard to come up with right now.
You don't need a license to autocross with anyone, and Evo school doesn't offer one. They do offer top notch instruction, however.Quote:

I appreciate your enthusiasm. It's good to be excited about amateur motorsports. Let me offer you some friendly advice as someone who has been doing this for fifteen years and has seen lots of people come and go and make the same mistakes over and over again - many of the same mistakes I made when I started.
- Autocrossing is a skill, and it requires practice to master. The best thing you can spend your money on at this point is seat time, seat time, seat time. You will need at least some seat time and experience to even get your money's worth out of an Evo school, so practice every chance you get.
- Don't throw a lot of money at the car right now. See point #1. You will spend thousands of dollars to make your car faster, just to get beat by some veteran in a 20-year old bone stock Civic. Also, adding all kinds of fancy adjustable suspension pieces to your car just gives you more ways to screw it up until you learn enough to know what you're doing.
- Don't forget point #1.
- There are a couple of exceptions to rule #2. You can (and should) buy some good street tires. Buy ones that fit the wheels you have now. After a year of doing this you might decide you want to enter a different class - or buy a different car - and it would suck to have spent a grand (or more) on wheels you no longer need that you bought because you thought you knew what you were doing.
- Don't forget point #1.
- Don't forget point #2.
That's my $.02. I wish I would have listened to that advice fifteen years ago. It would have saved me a lot of money and frustration as I was learning this sport.
Very good advice Iain. I really appreciate it. Please understand that I've been wanting to do this now for about a decade. Now that I have a car, I'm a little bit like a dog who's owner just came home from a day at work. I'm bouncing off the walls to get out there and drive. I realize this is obnoxious. Keep the newspaper swats to the nose coming (not you, but you know what I mean) and I'll settle down eventually.
I'm not really trying to beat anyone right now (other than challenging myself to do better than some of the other novices if possible). I realize it's a skill thing. Riding in Jerrett's 110 hp car and throwing down a 60 second time with my weight added to the car was plenty of an eye opener about skill vs. car. Don't get me wrong, he's got that thing setup on rails. But he also drove the tires off that thing. Should have seen the look on my face as we entered that first corner.
That said ... this is a hobby of mine. It's ok to make mistakes. That's part of the fun of it. I need an outlet for my energy and enthusiasm. The more I think about these things and bury myself in details that are way ahead of my skill level, the less time I spend thinking about how much I miss my wife and all that S@#$. This is therapy, except when it isn't. ;)
So ... I'm sure I've rubbed some people the wrong way. Believe me when I say, I do value your input. I'd like to lower my car and begin adapting to the tighter suspension. Why? Because I've saved up the money ahead of time and want to. If that pisses people off, there's not a lot I can do other than say ... sorry.
Thanks again for your input, I appreciate it.

Here, I'll do it for you:

Next step, pray they fit.
Without a fender roll, 9" wheels will not fit. Ask JimH about a shredded set of week old star specs. Fortunately, its very easy to do a nice roll on the NC. Take it to TDR, they have done several NC's.
What tire size are you getting? Even though you can run as big as 255, I've found the 245/40 to be a very good size. Also, some brands are wider than other. Remember: the contact patch is the same size whether you run 235, 245, 255. Only the shape changes. Picked a specific tire yet? I've driven most of the choices, if you'd like any feedback.
You should get in contact with TXCoyote on here; he built an STR 2012 PRHT last year and can save you a lot of trial and error.
A counter point to a lot of the advice here. Modify the car however you want. After autocrossing for a couple of years you'll have a better idea of how serious/competitive you want to be and what class you want to compete in. Build the car for how you want it on the street, that's where you'll spend most of your time enjoying it.
If you find that you want to compete then it'll be time to make some decisions about how to modify the car, buy a new car or co-drive a car that is already properly prepped for a class. I started in a pretty modified M3 that wasn't a class killer. I learned a lot in that car and prepped a Miata for stock class when I decided to be more competitive. No regrets here at all.
My only suggestions are to stay on street tires and have fun learning. Seat time is king and ask for instructors to ride along. Good ones will teach you everything you'll see at an Evo school.
