The car has a 9" rear with 15" brake conversion, DSC sport controller with their Tractive active coilover suspension, and MoTeC ECU handling the boost and traction control.

I'm looking at getting a street setup for 40/60 rolls with Forgeline beadlocks in 17/18 x 11" rear and need some guidance on tires between Nitto 555r2, Nitto NT05R, Toyo r88r or RRs, or M/T Street R. Based on what I'm reading, I should be able to fit a 325 tire. Max tune for the street is 1300 whp on E85.

I use MTETS 325/50R15 at the strip and a Toyo R888R 325/30R19 on the street on dry days above 40F. The Toyo is fine rolling with TC on but does not handle my power well with TC off below 60-70 mph. I actually came here today thinking about starting a thread on ultra-high hp warm dry street tires.

That's helpful info. I don't understand how those 2000whp Calvo Vipers can run 19" Toyo R888R on the street and still hook when rolling.

I'm thinking of going with the M/T ET R P325/35R18 for my street setup and keeping the P275/60R15 for the strip.

Good idea to start a thread on this subject.

Suspect those cars are running MoTec (or equivalent) ECU with advanced traction control…

Same. I’m running MoTeC M180 ECU with traction control and controlling gear shifts (pneumatic) on the 6XD sequential gearbox. DSS 9” rear end. I’m still thinking I can put more power down with the M/T since it’s the stickier tire compared to the Toyo.

You have built one heck of a beast, so I'll just go ahead and say it:

pretty please?

Wow, and I thought I had a lot of work into my car…holy cow…!

Great build! Ever run the quarter mile or are you only roll racing with it?

Thanks! It's been a long and tedious process.

Haven't raced yet. Car just got finished. Will quarter mile, 1/8th dig, and roll. This rear end and gearbox make it easy to re-gear. Goal was to build a fast Gen6 that is still streetable.

You’re quite welcome. It’s a killer build.

Out of curiosity, what is the new curb weight? On a good quarter mile run I’d guess you’ll jump right past the 8’s and hit the 7’s…!

Smokin19 · 06-23-2023, 06:28 AM

WOW!!! Can't even imagine how you could hook up on the street with anything other than drag tires. I thought I had problems hooking up.

I need to ask Prospeed what the weight is. I know they weighed it to dial in the new suspension. We’ve made some changes since, so need to re-weigh it with me in it.

I ordered Toyo 345 yesterday. I put these 325 on it back when it was a 1.7L, but they now don't even work with TC on.

Hey @ATP, what did you settle on for wheels & tires? Any updates on your build?
