Mods for HPDE
Nothing like putting that beauty to work on the track eh?

So after not feeling ready for the event in April, I pushed my HPDE to the NCR SCCA event at Rockingham that happened last Saturday. Out of my planned mods I completed the Koyo N-flo (R1443N), Defi BF oil/temp gauges, midpipe with Borla XR-1 welded in, and maintenance items. Didn't change out the HPS pads.
The car performed superbly. No fade in the brakes and a peak track temp of 197 F. The only hitch I had was rubbing of the right front tire with the fender well which stripped some wires. I "fixed" this during lunch by just re-wrapping the wires and zip tie-ing them out of the way. It looks like the upper rubber shock mount on that side is destroyed/crushed letting it sit a bit lower. So I'll have to take care of that. Thanks for all the input guys and helping me make my first track experience a good one!

I always had a problem with rubbing on bumps on the street if I had a big passenger (no not my girlfriend), but it was fine when I was solo. Unfortunately my instructor was a big dude. Awesome guy, but a big dude.

The compression on the passenger side front is massive in ovals. A worn bump stop would give up pretty easily there. I've seen tires absolutely punished to the cord in short order at Rockingham.

Yeah I talked with Ray and it's $60 per corner for the shock mount kit which includes the bump stops, so they'll be taken care of as well. Rockingham is very rough on tires. Fun though.

If you're looking for a good set of track day brake pads, try a set of Nick's (N-Tech engineering) Lapping Day pads. They'll give you what you need on track, but are livable to drive to and from the track with.
What's particularly good about them is their ability to handle the heat of successive hard laps, but also have good stopping power when cold, which is crucial in beginner run groups, because you'll get stuck following slower cars alot. They operate well over a broad range.
Be sure you have appropriate, fresh brake fluid! ATE Superblue/Supergold is what alot of folks start out with, because it's reaonably priced and easy to see when you've flushed the old out because it comes in two colors.

My brake fluid has been changed so many times it's not even funny (due to rebuilding all four calipers, upgrading to the 929 MC, and putting in SS lines). I've used ATE typ 200 but I also have superblue.

I'll second the notion on the N-Tech pads. I put in a set of N-Tech competition (one step up from the lapping day) compound and ran Summit Point main last week. It rained the whole time, so speeds and braking points were very conservative. They still had good bite and consistent grip every time I asked for it. They were also plenty tame for street driving. I have little worry that they'll also work fine when I get them good and hot.

I'm pretty set on trying the Carbotech's out first. The guys in msccnc.org have FDs, run tracks I'll run, deal with the weather I'll deal with, and absolutely love their XP8s at the track and on the street. If it turns out that they don't suit me, I can always change again.
video/pics?

If you like vir, you should join the tarheel bmw club. we run at vir three time a year. All the other club goes to alot of difference tracks, but tarheel only goes to vir, it is a fun club to run with.

Yeah I've been keeping an eye on THSCC, tarheel BMW, the local PCAs, and NCR SCCA for events. They seem to be the ones in the area with the best reputation. I think I'm heading out for the SCCA autox novice school in late Oct then to VIR with carolina PCA in late November.
