Wear on outside of tires - suggest suspension upgrades?

[wparsons]

That's nothing That's not really uneven wear at all, just using more of the tire width. It doesn't look bad at all. If you see a major difference in tread depth, or are wearing way over onto the shoulder then you should change something, but based on the pictures I wouldn't worry at all.

From last year, I've got some wear another 1/4" into the triangle now, camber bolts maxed out, swift sport springs, running about 37psi cold.

If anyone's interested - here's some gopro footage of one of the later sessions that day. Remember, I'm a complete noob!

You're not wearing the tires too badly, but you definitely need more camber.

RaceSeng camber/caster plates for the front, SPL LCA for the rears. You won't outgrow either one, and you'll get the camber you need now.

High end dampers are available as just dampers without top hats; all you need is the spring perch, bushing/bearing, and top nut ($160 total), and you continue to use your RaceSeng plates.

Please don't wear motorcycle helmets, get a proper Snell approved helmet designed for cars..and, the outside wear looks normal considering the amount of camber..

I'm far from convinced that, short of a HANS-equipped helmet, anything over a cheap DOT helmet is really going to make a difference. I don't have a roll bar. I don't have a turbo or flex fuel kit to burn the car to the ground. SA helmets cost more, usually have less visibility, and definitely offer less choice. I HATE my SA2005 Pyrotect. The only reason for a beginning driver to get an SA is, from what I can tell, to allow them to drive in events that require an SA helmet. It just sounds like a marketing scam more than anything. Not like Snell has a perfect history of testing. The 2005 designs are supposedly unsafe in smaller helmets.

you don't need to have a roll bar to benefit from a helmet specifically designed to take multiple hits (as opposed to one single impact with motorcycles) and even stock cars can catch a fire in an accident..

The HJC AR-10 he's wearing is an SA Snell rated helmet that has attachment points built in for HANS device; the logo on the back is specific only to the HJC automotive racing helmet line - hence HJC Motorsports moniker. Know your helmets...

Tire wear looks absolutely normal...barely scuffed in.

OP... one suggestion would be using your gearbox more. Is there a particular reason you really didn't shift at all after getting on track, going into slower turns with the engine in the absolute worst part of the torque dip? Being in the correct rpm range makes a difference in how the car sets the chassis to turn in. The car won't turn as well when bogged down verses when you are in the power band and able to control the yaw much better. You need weight transfer to better control turn in...whether under braking or acceleration - being in the torque dip range is not good for weight transfer.

The two go through the same testing; unless you're in a race car, there's no appreciable difference.

The difference in testing standards is fire resistance (non-issue unless you mess with your fuel system), and multiple impacts (to simulate hitting your cage/roll bar).

The difference in design is the opening for the visor; motorcycle helmets typically have superior visibility.

@Vracer111 thanks for the comments - Yup, didn't shift much, this was my first time out, and decided to work on lines and keep it simple that's a a great point you bring up about how it affects balance and turn-in, hadn't thought about that.

wear doesn't seem that bad


but given the amount of offs you had it did seem like you scrubbed yourself off the course a number of times... curious why you simply didn't apply brakes and went on your way?


keep an eye on those hot pressures. Too much air in a street tires for many laps (and it was also a hot day) will wear them much quicker.

Interesting point on the triangles. I noticed the other day that the triangles on my front tires are almost worn out, and I've got some chunking on the outer tread blocks.

I think I need to put some camber bolts on my car before my next track day and probably inflate my tires higher as well.

I'd attribute it just to inexperience, wasn't comfortable slamming I the brakes. ABS was kicking pretty hard during the day, I'm still on stock brakes and lines. Will look to upgrade these before I heard out again. Thanks for your comment!

not ABS, it was your traction control, which you've left on, if you look at your own video you can see the thing blinking every time it engages.. which was a lot


while it can certainly keep you safe in a structured environment, I would suggest you start practicing with it off as soon as possible, those counter-steer skills and feeling the back end coming loose are absolutely vital




having said that my first time in the car at MIR I left everything on, lol

@7thgear thanks man - gobbling up all the advice I'm getting, this is why I love this forum community.
