got my car on track a little sunday.
no big issues, but I have a bunch of little things to do.
basics I discovered.
minor issues
-my Stance suspension kinda sucks, but that is not really a surprise.
- my rear RB sway bar is a little thick, if I pull a corner at all the tail comes out, going to try stock, got one for 20 bucks.
-need a better oil cooler, or a relocation or better ducting. oil temps got up to 250, then I did half a cool down lap.
-getting some major heat soak, need to do some testing
-brakes got a little spongy but not that bad. will add vents to start with
- hard dog roll bar harness attachment point failed tec, had to pull the seat and attach the stock seat belt so I miss my first session.
one tire rubbed a little, the previous owner trimmed the front fender so I going to trim a little more on the driver side to make it work.
the good
I installed a track speed engineering radiator and the coolant reroute and built a under tray. water temp was a non issue. I cant compare to the koyo unit the car had but overall I'm very pleased with its performance on track.
stage 8, inconel studs and resbond. no problems here so money well spent.
over all it went pretty good for a first event, nothing broke, zero oil leaks, no coolant leaks

the issue NASA tech had, was not the harness or the attachment point but the angle from the mount to the strap pass through on the seat can be no greater than 20 degrees I think the guy said. he said, remove the harness and set up the stock belt. I wish he would have asked to just move the pick up points to the stock seatbelt spot. but whatever they have a lot of cars to look at. whatever it is for safety, but they did not look at anything on the car at all just my seat setup. they looked under the hood and said, this thing should go ok, have any brakes? yeah got brakes I said.

Which track? What brakes? What's your oil cooler setup look like now? I'm not sure what all you have but start with track pads and fresh fluid, and perhaps brake ducts. that will get you very far for not much money.
My only time on track with my car was before my brake upgrade and they flat out sucked.

I run motul 600 fluid, and the good win racing brake kit. the brakes got a little soft but then I discovered a minor fluid leak, which means I need some new seals,
I am pretty shocked at how well the brakes work, I was freakin leaking brake fluid and the car still stopped awesome.

when I got the car it was set up with a 4pt, but the cam lock was compatible with a 6pt so I bought just pt 5 and 6, and left it alone.

Never really complained about mine and I think its probably closer to 25-30*. I am not sure I would have made you use the stock belts though, that seems more dangerous than a 5/6pt, but I am probably not the best person to judge this.
I don't know about that. I would be getting worried at 270*

so how near 300 do you think? 280 still ok? my gauge goes to 350 for some reason

Anyways, as you will notice in a couple of threads, the temperatures that most people start to worry at is different from person to person, but generally 300* is the maximum and I would back off 30* before that.

220-230* is what I've heard as ideal for oil temp. I wouldn't base ultimate hot oil temps on when the thermostat opens, as consideration is given to warming up the car with that. I've run a little bit around 300* (few sessions with the 280* gauge pegged) and it wasn't the end of the world, but I wasn't totally comfortable either.
Track, you're totally right, different strokes for different folks Oil choice has a lot to do with that also.
The "8K" of a spring is 8kg/mm. Multiply by ~56 to get lbs/in.

Those are 448/337 lb/in springs. That's going to be way too much rear spring for those sways or way too much rear sway for those springs depending how you want to address it. You should be seeing oversteer with your combo and it sounds like you are.
A better match for the grip of your NT01s would be going to 550lb fronts with your current rears and keeping the RB rear bar, if your shocks are good enough. With 450lb front springs, similar sways, and less sticky tires than you I was on the bumpstops in hard cornering at the track. No bueno. I learned my lesson.

thanks for the help with the spring rates. I was thinking about buying at least one set of springs but hung up on other stuff. just wanted to see how it went. I was thinking about putting the front springs on the rear and buying a new set of fronts but that might be too much for the shocks.
I need to get a dyno chart for these dampers, I really not sure they had handle super aggressive springs though a rep said they would be ok.
yeah, it was not the best but I was able to drive around the issues. any mid corner correction before track out and the back end would start to step. I knew I was going to have some issues but it wasn't THAT bad. I just had to pay attention. I know the track pretty well so that makes it easy. autobahn south (someone asked.)

Get two of these for the front for $70 total and it will be fine. You can leave the rear sway alone. Balance will be yours.
