Tempting! although I already pee in my firesuit at 158mph at VIR...

He did a lot of testing from 245s up to the expensive extra wide 275 A6. He said the TT director couldn't believe how fast he was with that few mods at Nationals.

Have to admit, I'm a grip fiend too! Inspires confidence... especially at VIR where more tire can help a lot through the esses

Ok. I'll be at RA Match 18 and AMP May 5. But I'll make it a point to stop by when your there.

Mike · 03-07-2013, 06:48 PM

I'm going to that Chin event too in May!

Z Ya there!

wstar · 03-07-2013, 06:50 PM

Yeah maybe more tire is best, esp with your SC setup. I'm still NA and I always feel like my 295 rears are just "too much" tire half the time. I'm struggling to get 'em to push sometimes when I want 'em to.

Mike · 03-07-2013, 06:59 PM

295s work for me, but I run them up front too.

Sounds skinny to me. 315 front and 335 rear on car now. Going all solid bushings to hold everything in place.

SPOHN · 04-16-2013, 05:55 AM

^ lol. That's my plans after track season to replace all bushings. Buying all them next week.

My sentiment on this is completely reversing course now that I have better suspension. The problem wasn't too much tire, it was too much slack in the suspension of the car

I ran 315/345 for 2 years. It worked well on the hot days but on the cold days the tires never came up to temperature during the session. Out in always sunny California it probably isn't an issue.

So there is new rules this year so I'm doing an about face and running 275 square BFG R1 and/or Hoosier R6.

Hi TravisJB! This is Greg, from Arizona, now florida...winning bidder for your car number! Glad I finally caught up with you! I gotta do a lot of reading backwards to find out what's going on with you. Looks as if you are racing in Virginia? ...a super-charged Z? Cool! Sorry about ur original thread!

So, here's what I ended up doing with my other rides...

Keeping the F250 ! Zless/Greg will be pleased!
Bought a Honda Ruckus ! I've been driving it to work and it makes my day !
Have a 135 vert on the way ! tricked out with pretty much everything... m package, perf, comfort, HK radio, nav, etc and sport suspension that lowers it 25mm with 2x spring rate and bigger sways

Z is waiting patiently in the garage!

Zless@arizona · 05-03-2013, 04:34 PM

Awesome to se that you are obtaining digital representation of invisible forces on your car. That is what it takes. I did not know that you were going to spend that much money when your project started. I'm am impressed!
