Couple Burnout Pics

[Scoobum]

Yours truly beating on his junk from June 7th. Your eyes don't deceive you. Those are MT 10.5's...and they clear the frame rail and wheel lips.

Nice! Nothing like a smokey burnout.

Very nice!!! What did it run that day?

Very nice!!! What did it run that day?

Bracket raced it that day on a 7.30 dial...equival ent of an 11.4. Boost pressure was 21 PSI. Low/high gear 02's were around 780 with Erics 110 race chip on the default timing settings.

what size rim and BS?

[Scoobum]

Larry, these are the stock GN rims...with the narrow sidewall MT 10.5's. Keep in mind that I run aluminum rear drums...so you'd likely need an 1/8th inch spacer to get the same results. I use the motorcycle track as the return road...so they do 'clean' the frame rails. If you check on MT's site...you'll note they sell 4 different 10.5's...with different sidewall measurements. These are the 28x10.5 x15S. I think the other one has a C after the 15. I normally grab up every pair of 28x9x15 slicks I can find on KIJIJI...as they have the same sidewall measurement as the 28" drag radial...and fit with zero issues on a rim with a 4" backspace. Grumpy ran a 4.5" backspace rim with a 1/4" spacer with a 28" drag radial. I just mounted a pair of 28x9 slicks yesterday with a set of Billet Specialty rims with a 4.5" backspace with an 1/8th" spacer...and they fit. I can post a pic if you like.

How big a difference is there in the thickness of the aluminum verses the steel drums?

[Scoobum]

I believe an 1/8th".

I recently picked  up a set of the aluminum drums.  Haven't got around to cleaning them up for install.  Different thickness never even crossed my mind and I already have 1/4 inch spacers on the rear wheels

Thanks Brad my T wheels would work perfect with steel drums 3 3/4 back space. The aluminum drums I have came off a camaro and had 1/8 GM spacers with them.
