Better acceleration with 13inch wheels?

Hi guys, I'm pondering on the idea of getting some 7x13 inch superlites for my mini but don't want to spend the cash, only to find it makes no difference! I'm running 6x10's with road legal semi slick yoko's at the minute but my problem seems to be traction. I've got a supercharged 150bhp a series under the bonnet and all it wants to do is wheel spin and pull me all over the road, rather than up the road! I know in theory that 13 inch wheels should dull the acceleration but I was just thinking the lager footprint of rubber on the road might be better? I'm taking it to Santa pod next weekend for mini in the park and want to see what it will do the quarter mile in, but I'm worried I'm just going to be sat on the line in a cloud of tyre smoke! The clutch is just like an on/off switch as well so that doesn't really help matters! I do really like Mini's on 10 inch wheels so I would be a bit sorry to see them go, but at the same time I want it to drive the best it can. Any thoughts on what would be best?

Hi Cooperman, thanks for your thoughts there! I do really like the fact that my mini is on 10's and a set of super lights with yoko A048r is going to be over £600. I could get an LSD for a similar amount of money so do you think that would be a wiser investment? Do you know how an LSD will change the handling characteristics as it pulls all over the road anyway on anything but a flat surface going in a perfect straight line! You can feel the individual wheels spinning up and pulling the car at the minute! I never use my car in the wet, it only comes out on sunny afternoons for b road blasts and I would like to do a couple of track days, so day to day practicality is not an issue. Do you know what type of LSD would be best? I've seen mini sport do quaife, sailsbury and trans x but I don't know the difference? Thanks again!

Thanks for your thoughts there guys! After a fantastic day racing up the strip at Santa Pod yesterday, i came away with a 15.1 @ 96mph. I think i could have got into the 14's but my poor clutch could take no more and started slipping. I was loosing so much time spinning the wheels in first and second gear, but then making it back up again once i got into 3rd. Even if i lost against the other car in time, my terminal speed was normally higher. I've decided after a long conversation with the guys at Swiftune this morning, to purchase as well as a new rally clutch plate and grey diaphragm, one of their Swiftune A.T.B differentials. Apparently they just behave like a normal open diff when you drive the car normally, so you get none of the heavy steering associated with L.S.D's but start working when you really start to push it! Apparently is should help with my torque steer problems as well. It's arriving later this week and i have to take the engine out and split the gearbox to fit it so i won't be fitting it straight away, but i can't wait to see how it drives after! I'll then be able to keep my car running on 10's which is what i really want as well!
