B4 setup

[woo12]

How do you get more grip on a b4.1 without paying over £20

[TommyG]

Additive might be a cheap alternative. Cheaper still play with your set up. What surface are you running on?

[peetbee]

More front end grip, rear end or all round?
What tyres are you using on what surface?
What's your current setup?
Lot's of questions I know but without knowing this we could end up suggesting what you've already got!
