Default Paging Bence13_33

Hey Shane,

I was just wondering about a few things on your car... What rims are you using.. If you still use the stock Rallies - you can get a .1 to .2 faster ET just by swapping to Centerline Auto Drag or other light weight rims.. The rally wheels are around 24lbs/rim.. The Centerlines are 14.5 lbs/rim.. That's almost 10 lbs per rim lighter.. Due to the fact that it's centrifugal weight - each 10 lbs that you take off is worth about 50lbs... which would make your car effectively 100 - 200 lbs lighter... which could take .1 to .2 off your ET..
There are some additional weight savings that can reduce your ET by quite a bit.. One example is the spare tire carrier and spare tire (if you have it)..

:cheers:

Olivier

I have currently already removed the spare tire, carrier and floor jack from my car. I am however still running stock Corvette Rally rims. I may have to look into a set of Centerline Auto Drag Rims. Thanks for the recommendation!

The Convo Pro's are pretty light too.. You can pick up a set of Auto Drags for around $200 - $250 on Ebay...

Some Auto Drag's or Convo Pro's in a 15x8 with 4.5" backspace would fit pretty good :yesnod: .

I don't think that you can get them with 4.5" backspacing.. My Auto Drags have 3.375 inch backspacing and don't stick out.. However - I have 1 inch flares on all 4 wheels...

Bence....

What are those drag radials you are running again? They fit right on the stock rally rims?

He uses ET Streets which aren't Drag Radials.. They are actually knit tires just like slicks..
