Hi

I have an ER14 and after running on astro need some advice on tuning. Car was pretty good but traction rolling an area for improvement.

Cannot find the part numbers for option thicker antirollbars mentioned in the manual. anybody know where i can get then in Europe. Will other brands fit?

Secondly, any shock position tips.

Thirdly any shorter springs or ways to drop the ride height lower than stock springs allow, feel I need 2-3mm lower.

Help appreciated...Car is pretty darn good out of the box though...
