Setup advice for 2wd buggy's on polished floor.

[Chris Elworthy]

Hi lads,

I'm racing my first indoor buggy meeting this Sunday and have been informed that the track will be Practically a 50/50 mix of carpet and polished gym floor. I'm fairly confident of setting my car up on a carpet track (I run the TLR 22 in mid config) but am puzzled as to what sort of setup and tyre choice will compliment both surfaces.
Looking at the yellow minipin tyres I can't see them working on the slippery stuff due to the small surface area? Can anybody confirm?
Also, how should I dampen the car?, will softening the oil to around the 27.5/25wt marker help generate grip and are there any other tips, axle height, camber, shock location? That will help?

Any advice would be greatly appriciated

Mini pins are good, but if your club allows it, stretch 1/8 foams on the rims and apply additive. For oil, go soft, but not too soft. 27.5 on the front and 32.5 on the rear should work. Stand up the shocks a little, and because of the roll, put 2° camber all round. It works for me! If you want more advice, try this:

I've seen that Bloomfield setup but I'd say it was more suited to a carpet track. 27.5 oil in the front and 32.5 in the rear seems odd? Would I not need a very soft oil/spring on the rear as around 50% of the track is very low traction polished floor including a high speed sweeper at the end of the straight.

Why don't you just try different combinations.

I do intend to try different combinations, i am simply looking for a starting point

you want the rear wheels as planted as possible.
so, you would ideally want the front shocks a little stiffer, that way when your on the corner on the slippy floor the front shocks dont work too much lifting the rear of the car up.
I ran my outdoor setup at chadderton where its pretty slippy, and it was utterly useless, donuting all over the place. so i went up to 37.5 front 32.5 rear and was miles better.
Experiment with the rear links as well. You wont know whats best for you till sunday

The main setup advice here is throttle control
