Is there something you don't like about your car the way it handles now?

Didn't take a pic then so I don't think you'd be able to tell now. Pads recovered fairly well, as there isn't that much need to heavily brake (at least not at the speeds I was going at... I only got above 80 mph at the end of the straight), except at the entrance to turn 4 (at the end of the straight), as it's a > 90 degree tight left hander.

I was wanting to get the Ferodo street/track hybrid pads (forgot the number off the top of my head), but what's Mu G-Four? Brake fluid?

Next track day in AZ isn't until October at Indy. Too hot. So, per my instructor's recommendation, I'll be retaking HPDE 1 instead of moving up to HPDE 2.

Yup, brake fluid.

It handles great. I just thought sway bars would be the next logical upgrade.

After that I need:
-Header
-AP brakes
-Fixed Seat

Then I am done for awhile!

If it handles great right now, then I wouldn't upgrade any more suspension until you can clearly identify some handling characteristic which could use some improvement.

This.

Time to move on to the rest :)

I'd recommend brakes ;)

What're the benefits of Mu G-Four over RBF600?

That and a header + tune (don't get headers if you don't intend to have the car tuned) will REALLY wake the car up. My car handles fine with the engine-back exhaust with stock brakes and pads, but then again I haven't tried it at really high speeds with that kind of power addition. I already can way more easily chirp my stock tires with the engine-back exhaust + tune than I could before, and I'm still quite a ways from the wear bars on the HP Primacies.

Tire question(s).


During my first track day (stock tires) my instructor extolled the virtue of learning on garbage tires, because it allows me to understand my mistakes far more than sticky tires, which he said cover up mistakes and slow the progression of the driver. He told me it'd be wise to not move up until I could trash a set of garbage tires in a few days, as then I'd be at the skill level where the higher spec tires would not cover up my mistakes and hamper my learning so much. Looking at my stockers after the track day... they still have a lot of life. So I guess I could push a lot harder and there's a ton more room to grow there. But I've also got a new set of wheels in the garage and was planning on dropping some solid rubber on them once I have worn out my stockers on learning on the track.


Help me decide- should I be going with more of a lower spec, intermediate tire next to continue my development? I see the DZ102s are only 100/tire in 225 size, maybe those would be a nice progression in my learning? I was originally opting to go for star specs/dzIIs as the tires for my new wheels, but thinking more about my instructor's guidance makes me want worse tires to learn faster. (He is a 20 year ITE racing veteran with uncountable podiums, co-driving dozens of different chassis, his personal ride is a 944 turbo ITE prepared car)

Keep your OEM wheels and tires when you swap. That way you have DD wheels/tires and track wheels/tires! There's no reason you can't roll in style during the week and switch out to the OEM setup for track days.

Not a DD car, not interested in two sets, additionally, not interested in track only tires because I'm now thinking of having more pedestrian type tires for track use as well.

Just did my second autox day. My progression is not as good as the first day. On my first day my worst ran and best ran was 13 sec apart lol. This time they are only a bit more than 1 sec apart. I kind of feel like the stock tire doesn't have enough grip but I also realize that it's probably better to learn on the stock crappy tire. I can't help but noticing that other novice frs driver was much faster than me by 3-5 second other only mods being better tire. At what point would one be ready to step up to better tires? If I were to get better tires would I ran better time even though I'm making mistakes?

For me, I learned faster with Direzza star specs. The car stayed on the track. The junk tires can teach you how to drift, not be fast and reach the apex's accurately.
