chassis set up?

Hi, I´m new to the forum, and I´d like to have some advice to set up a brass 1/28 chassis with a 16D type motor.
I live in Argentina and 1/28 is a common scale here (we race 1/24 and 1/32 too), perhaps you are not too familiar with 1/28 since I couldn´t find anything on the net about these...

What I´d like to know is about the front end of the car (guide, front axle, track clearance, etc), to make it tighter or looser. The track I´m going to race at is a fast one with generally wide turns.

If you are not familiar with 1/28, perhaps your experience from 1/24 might help too...

So, any help??

Thnx a lot!!!
