I will add that if anyone wants a custom made wilwood kit i can connect you with the person who makes custom race kits that did this one. It required me buying the front and rear knuckle / hubs so he could use them to measure and machine brackets and engineer fitment etc. so he had the specs...

I am on my second set of studs and have had some loosen but I am changing tires a lot between race slicks for time trails and 100 tread-wear for the hpde sessions. So at least 2-3 times per track day. I now am in the habit of checking by hand each tire change to see if they are snug and then...

Have you checked the charge pipe connections. The after market ones with the rubber connections in the middle tend to come off especially if you are running high boost

Great. Now come over to Az tracks and we can connect. There are events with different clubs every weekend in march. PCA at Inde, NASA at podium, and Pro Auto at Firebird. I will be at all if these. Look on Motorsport reg to register

That is true. I am just cheap and for hpde sessions when they fall off i just try to adjust to make up for it but for time trail yes i have to balance heat cycles and tread wear and as you say you cannot run all the way down even when they still look like they still have tread left.

These are great shots and good you are driving in the wet as it gives you more confidence on car control when you are back on the dry. On driving the tires until they cord. Just remember to get under to check insides especially as you start getting to higher camber. Was watching the outsides...

I agree that it is not just installation on the old bolt. I ran through two sets of these. And they were tight. In fact the stupid nut on the first ones was so hard to get tight as it us a metal tab lock vs nylock I had to use two big beaker bars to get it on plus the torque wrench. I can see...

Just to add in support of SPL. I was one of the first to break these bolts. So I talked to them even before they had the new ones redesigned. They have been very good support wise and they sent me the spherical bearings as well as bolt to change. I have all their arms on the car and 80 + track...

Also for others if you still have the original bolts they will need to be changed. I broke both of them on track and luckily in Both cases was able to to go off track straight and stop/ get back to pits. But this is a bad thing if you break one even on the street. Here is what it looks like...

Agree with razorlab. I too have the new stud and they are shorter and fit 18” wheels no problems. When they first revised the bolts they were too long. So just need to get the. To send you the correct one.

There have been some other threads on this but if you buy a power bleeder with a European master cylinder cap then this easy to do with out trying to have someone pump break peddle etc. you do have to pull the wheels. So if you have a jack power bleeder/ catch bottle you can do this yourself...

Two of these looks rolled a bit on the outer edge ( expect those are the fronts) so is getting close tread wise. I would have your next set ready and run them till they cord if they still are not sliding all over the place but I am cheap :). They may not make both days. So 9 days you already got...

Glad to see you are hitting the track. I have been at chuckwalla it is a fairly technical track and the bowl/ high bank turn is unique to most of all the road courses in the area. There is not much you can adjust for alignment until you go to camber plates and or adjustable arms. For two sets...

I found the nankangs to last a bit longer and times are almost the same as maxxis for hpde sessions. I now am running p zero slicks for time trial. But that then puts me in tt2 class for Nasa. It takes a bit of adjusting to as you switch back and forth but you gain about 2-3 sec faster on the...

I bought my Laps no subscription so works fine will all the tracks I have been to. I also have a solo2 as some do not always run Mylaps outside of the competition groups.

I run 275/35/18 and have used 3 sets of the maxxis. Hot temps I have tried 30 to 36 and ended up at 34 seeming to be the best. I have corded the out side fronts at about 4 track days even with different camber and pressures. So they tend to roll the edges more than some of the other tires...

Can you describe what it is doing. Pulling to left or right when you hit the bumps. Do you have to counter steer to keep it straight or More of a body roll feeling. If you let go of the wheel does it pull left or right on a straight road? Not sure what wobbly means. There are not a lot of...

I have basically the same on a 2021 with no tune or jb4 and have Dyno at 420 hP to rear wheels.

So there will be a lot of opinions as to what you need but after the helmet, then at a minimum you need an air pump , tire gauge to adjust pressure and pump up after for your drive home and then a torque wrench/socket to check an re-torque the lug nuts after the first few runs. This is even more...

I am glad to see more interest in the Toyota Nasa GR driving experience which now has all the GR cars. Supra, Gr86, Corolla etc. I am a NASA instructor for Arizona region and a Supra owner. So if there are any of you on the fence about doing your first track day in Az just reach out. Look...
