Being that you're gonna use a regular radial street tire, the weight between the two is probably negligible. So use the taller of the two tires for best et.

 

Update:
We´re having a bracket race event at a local track this sunday so i put some crazy hours into the truck this week to have it ready





Shocks are at 5 degress now

Had some poly bushing made

Ended up going with the 235/65-17 tires


truck got a little higher in the back with the new wheel combo


Forgot to take picture of the traccion bars, will post them later

 

Nice work man. Post up some numbers when you get them.

 

Looks sweet!

 

Looks good!

 

Looking really smooth!

 

Update:
Had a good weekend bracket racing, was able to accomplish 3 important things:
-Not break anything
-Make my first 12 second pass ever
-Bring home first place in the biggest category we have here

My 60 feet arnt there yet but got a little better, i need a locker, 2 step and meth to run more timing, really hope that will bring it down to atleast 1.7x

Overall the truck went 0.4 faster this time then the last 2-3 times, im sure lighter wheels helped, maybe i use to have problem spinning a little after 60 feet not sure
Passes where made at 10 psi of boost and 8.5-10 degrees of timing

 

Crazy DA

 

Should be able to run alot more timing on 10 psi


Whats up with that mph?

 

My IATS get to high (140+) and start to see knock if i throw a lot more timing at her, we only have "91" octane fuel here local

Its km's in miles it would be 114.79



114.79
