Default Street/Track to mostly track build

Plain Jane 2008 with ugly rims that came on it.


Hit some scrap on the highway and ended up with a V1 bumper and did white vinyl by myself.






Wrapped it up with 285/265 RS3'S on RFP1's



Diff bushings, Akebono brake kit, hotchkis sways, and trans go installed over winter. I did a stillen grounding kit as well...but that was because I missed the electronic shift connection point when I was doing the valve body and couldn't figure it out.






Finished up trans cooler and gauge.






Test pipes, CAI, and Z1 upper plenum done as well. Mostly for sound. Didn't expect much gains but it runs pretty good after a tune.



Need coilovers or shocks next. Still deciding and learning.

Welcome and what kind of track build are you on? SCCA? NASA? Just local track days?

No plans for any organized racing just yet. I will be doing track days once a month this year. I just like tinkering with cars so just for fun at this moment.

Next stop is Road America on the 15th.

Have fun and stay safe!!! If i were you id pick the sanctioned body and class you are going to race in before doing any major work on the car... many classes dont allow certain upgrades or give you a handicap because of them.... best not to waste ur money... ask me how i know

Perfect weather and learned the track pretty quickly. The cooler solved the shift slipping issues. But let me tell you, 4th gear (auto trans) is absolute dog. It felt as if I went from 3 to 5. Only got up to 130 on the front straight.

No other complaints, rear end got a little squirrely a couple times. But I did manage to get sub 3 minute laps the second half of the day.

Mvp track time was the group. Did 3 events with then so far, seems well organized and safe.

What pads are you running on the Akebonos?

I was running EBC Blues but only getting 3 track days out of them on a combination of Homestead and Sebring. So I switched to Hawk HP Sport + but they squeal like crazy on the street.

Carbotech xp 10 in front and 8 on the rears. They don't squeal at all but they are pretty dusty. Stopping power is great tho. I only have 2 track days on them so far. I've been meaning to pull them off and see how much is left

Didn't see "on the street". I only use these for the track so I don't know how they sound driving around town.

Finally got around to pulling the pads. Still plenty of thickness left on them. Cleaned them up and will run it again in a week. Local track, Autobahn Country Club in Joliet, IL.

Didn't do anything else to the car besides fixing a few spots of vinyl and that was it. White vinyl might be coming off soon. Quickly realizing it was a bad idea for the track.

Season is about over for me. I hit the local track Autobahn Country Club last month and bested my fastest previous laptime by 10 seconds. On a semi wet track.

Just came back from Road America this past weekend. Terrible weather but was able to get a couple decent sessions in. Didn't go any faster but I was right on my personal best on a wet track. So atleast I'm seeing improvements.

I like working on things so I'll do something over the winter, just not sure yet. Probably Koni yellows and swift springs.

Set a personal best last week at Autobahn with the same setup so that's nice. Running the stock radiator with an external trans cooler and it was getting pretty warm. Wondering if upgrading the radiator and only using the external trans cooler would help.

Also debating on shocks & springs vs a LSD.

If your transmission is running hot I would do three things, these have resolved all my issues even on hot days

1. Add a larger pan to increase capacity

https://www.yourcovers.com/transpan_11091.php

2. Make sure your external cooler has a fan, when I added a fan there was a big difference in temp

http://derale.com/products/fluid-coo...3-271226240719

3. Get a thermal wrap for your hoses that run to the cooler. Those hoses pass right by your headers and get pre-heated going to and from the trans.

https://www.pegasusautoracing.com/gr...D=HOSEINSULATE

Since I did these three things I have had no issues with over heating the trans even in 90 degree weather

Thanks for the ideas. My cooler is mounted on the front of the radiator. It gets plenty of air so I don't think a fan would do much. Nor are any of the hoses by the exhaust. Everything is upfront.

I definitely will be looking at a deeper pan though.

OK, my cooler was mounted in front of the radiator and the fan made a difference and the two hoses that run from the transmission to the cooler run along between your block and your exhaust manifold/cat and that's a pretty hot area when your on the track for 20 minutes.

Good luck

Oh interesting, I didn't think about the stock steel lines coming from the trans itself. I'd say its worth a shot.

Well the stock trans cooler has been bypassed with the new radiator in. Its almost 100 degrees here today and the trans never went over 185. I did notice its moderately overfilled now. Maybe a half inch above the hot marking. Will drain some tomorrow and hope for the best at Road America in a couple of weeks.
