this has too much spring rate for track also. aero wont work well with this ride height

 

My next tire will be a 265 A052. I think the car will be very happy.

 

You forget you get +2 back for mechanical throttle body now, so really the .1 is moot compared to the added grip you'll receive for extended laps. Though I'm in the same boat, struggling to fit 295's without trimming the voltex goodies in front.

 

Do you think there's any hope of tucking those wheels at full compression?

I removed the springs and fully tucked my 18x10 setup when I was doing fitment. It took some fine tuning but it doesn't rub anywhere under compression.

If I went with another 0.5" of wheel I'd have to take most of it from the inside clearance, though. That becomes harder to judge at static compression because tires flex inward under cornering.

 

For the rears, i think there is still atleast 10mm to the frame, just need higher offset wheels and/or lower profile tires. I may try revisit the camber bolts much later. If I do tuck that in then the front would be tracking wider

 

FWiW if you're playing the P/W game and you're not on track for more than 15-20 mins I'd take the extra power over more tire. Especially if you're running at larger tracks.

 

That card isn't playing out like we'd think it seems. Last weekend folks switching to the RR's are 1-2 seconds behind those on A's still with 50hp increases in TT. Well known guys with solid teams and cars. Goes back to that old saying, if you can't put the power down. But I think that's mostly due to time and setup. There's just far to many options now for anyone to say "here's a baseline" like we have for the purple crack. And these 200tw's don't last "on the shelf" nearly as long as hoho's before they switch them out for the next model. The 100tw's and below like NT01's and such have had that time but it'll be interesting to see the long game results. I think they're still short on power to make up the real difference. Plus lots of these cars don't have "all" the aero to maximize grip to a specific tire like you're seeing in WTAC.

 

A Toyo RR vs a Yoko A052? Yea that's not surprising in the slightest, the A052 isn't using a compound that's decades old lol.

I'm talking purely about widths here. Compound will always play a much larger role than width. I would still be looking for more power over more tire assuming you're on one of the competitive compounds. I can't imagine many of those other cars are AWD.

 

I'm thinking of trying @ayoustin rear camber locks on the upper control arm + standard camber bolt to pull the wheel in an itsy bit. worth a try right?

 

The upper arm is not adjustable. An adjustable arm is the only way you'll be able to change the rear track. I've talked about this with Dallas before but we concluded the market for such an arm just isn't there.

 

hmm there's got to be an offset bushing we can use. honestly I cant remember how the upper control arm is mounted

 

The bushings are too small to have any amount of appreciable offset. Aftermarket arm is really the only solution.

 

I was keeping this around in case I feel like retrofitting it :P

Nah the RR vs A7's. Using the RR gets you the max 1.6 plus if you're doing the 275 width inside the 282mm gauge. ao's are only 1.0

 

RRs have never been a competitive compound from what I've seen. I would fully expect a car on A7s to manhandle a car on RRs if they're within 100hp of each other.
