Props for getting out there and driving, and posting it!
As long as your setup doesn't totally suck, try to focus on the driving more than the car parts (I know it's a hard thing to do, and I mostly failed at it!). It doesn't really matter how your time compares to anyone else's. All that matters is your time keeps getting better as you learn to drive the car. While it's helpful to read books and attend classes and think about all the conscious aspects of driving, I firmly believe at the end of the day the real core skills are sub-conscious, and there's just no better way to build them than to keep building up seat time. Once those are there, the rest is more like high-level strategy and planning. |

Congrats, now go back. Ask for help from experienced drivers...I know it may sound crazy but ask one of the faster guys to co-drive your car with you after you have done a few events. You will be shocked at how fast your car can actually go and learn a TON!
The most important Mod for the car is you. |

Seat time, I get it. But can you polish a turd (Mythbusters not included)? My friend hated the HTR z3 also on a WRX so... So if no one can comment on what I felt vs what i have setup, then I'll just go with what I had in mind. Splitter, tires, roll cage.
What does a scca event have to do with anything? I googled ohio autoX events and went to one. Happened to be a scca event for $40 for 8 runs. Sounded good to me.

Oh yeah before you even talk about setup, you might want to scoop up a set of R-S3 for cheap and start with that. You will chase your setup forever and not find as much time as a set of tires. Last edited by cossie1600; 08-19-2014 at 01:36 AM. |

![]() I wouldn't even bother with aero mods at this point (splitter and/or a big functional wing). I've been doing road courses for 3 years now and I'm running a pretty decent pace and I still haven't added aero to my car. The aero mods aren't going to help you feel the car or learn to drive. They'll reduce lap times for a good driver, but (and I don't mean to be mean) you need to learn to be a good driver first, and then worry about aero. If anything aero will hold you back in the initial stages. It makes the high-speed corners counter-intuitive because the limits don't change linearly with speeds. Even ignoring the non-linear effects of aero, there's also that it's just going to take time to learn the feel out the tires at the limit. Figuring it out on a mostly-stock Z is already going to be tricky and dangerous. Instructors and safety rules help a lot, but the bottom line is you'll end up spinning and/or going off track a number of times during the process in the long term. Doing that at lower non-aero traction limits is going to be way easier under lower g-forces, and less-violent. That and off-course excursions tend to eat splitters anyways. Back on the seat-time thing: MSR-Houston was the first track I ever drove at. My first time out was in a very low-traffic open-lapping day with no instructor at all (which, in retrospect, was kinda stupid), and my lap time was about 2:09. Fast forward almost 3 years of gradual learning through an instructor-led process at DEs and I'm hitting 1:48-1:51 (diff tires). That's an 18-21 second reduction. Throughout the process I've done some upgrades on the car, but I've analyzed this stuff over time and at best 1/4 of my laptime reductions came from car upgrades. The rest just came with seat time. Or here's another data point: DR_, another 370 driver here on the forums who's a much better and more-experienced driver than I am, still beats me by about 4 full seconds in best lap times posted at a different local track (TWS-CCW). What makes that hilarious is his car still has a full stock interior, no rollcage, and missing a bunch of the other extensive modifications and weight reductions my car has. Like cossie1600 said, invest in some decent tires. It's hard to beat the RS3 as a good streetable tire choice. If you're really worried that something specific in your car setup is bad enough that it will inhibit learning, have an instructor drive a session in your car (in an advanced group if possible) with you in the passenger seat and then get their opinion on any necessary changes. It's hard to beat the input of an experienced driver actually driving the car. Also - it's a good chance to see what kind of times they run in your car. Even though it's a foreign car/setup to them, it will take you a long time to get close to their times... Last edited by wstar; 08-19-2014 at 03:50 AM. |

I get your comments about aero but look at my setup again. You say DR for example is faster than you. Well his car is better than mine I assure you. My rear end is 7% lighter than his. You can be a fast driver but I don't think drifters are as fast as road racers. Right now I have a drifting king with these tires and super light rear end. I know no one will believe when I say I hit my max in this car but I pretty much did. If I can't touch the throttle without spinning out I don't see how anyone else could. Tires, a role cage adding weight and a wing pushing down on the tail can only help at this point. I'm not ready to remove the front windshield, AC, dash etc. to get weight back to neutral. I'll go with some tires here soon. Still not 100% what I want. The RS-3 will force me into a 285/35/18 square. I just want more. I can fit maybe a 295 front and as high as a 315 rear. Still weighing my options though. I know people say square for rotation etc, but money aside, what would you run if you could?

I've driven my car in the past in the kind of state you're talking about, where I had the rear half of the interior completely gutted but it was mostly stock from the seatbacks forward, and no cage. Mine was like that for several months at one point. It made suspension tuning a little trickier to keep the car from oversteering too much, but even when it felt wrong to me it was still totally drivable and controllable, and spins/offs were rare and totally my fault. At the time I ran 275 front tires on 10's and 295 rears on 11's and that was enough stagger to compensate (and using the soft setting of the Hotchkis rear bar). The fact that you have these huge spring rates as a starting point could be coming into play as well; you may just have to buy some weaker rear springs for now until you finish the rest of the car's setup. When you say things like "I can't touch the throttle without spinning out", it's hard to interpret what that really means. Does that mean you're entering corners too hot (under-braking) and thus not leaving enough speed on the table to apply throttle at track-out to stabilize the suspension? It's hard to imagine, even in its current state, that the car is so oversteer-crazy that you can't use the throttle on track-out at all. I didn't miss somewhere that you put forced induction on the car, right? Even if the car is a bit too over-steer happy, you should be able to still use light throttle and correct with steering angle and adjust your reference points, etc and get the car to drive. Earlier on in the first post, you mentioned that situationally sometimes you got massive oversteer, and other times the car simply drifted straight sideways. That sideways drift is what should happen in a reasonably-balanced car as you throttle up at track-out. Going a little "loose" and over-steery intentionally you still have that sort of behavior, it's just the angle of the slide changes and the rear slips out a little faster than the front does at the limit, but both ends should be slipping to some degree. It's a small degree, though, not a drifter-type slide. Maximum traction on most tires you'd ever use on a track occurs around the ballpark of 5-10% slip angle. The traction of the tire builds progressively as you add more lateral g's up until it begins to slip, then keeps building for those first few percent of slip. After you cross over that peak and keep slipping at harder angles though, the traction on most tires falls off a cliff pretty dramatically, which is where you start losing control of the car. Generally speaking the grippier the tire, the more spiky the traction peak is (meaning you have a much smaller optimum window to play in before you hit that dramatic dropoff in traction). Quote:
