I need some suspension advice! I bought a 914-6 track car last spring and it is very soft. I don't know what I have installed yet but I suspect I need an upgrade over the winter. The car is a 2.8 liter with full cage. Any recommendations as to torsion bar size and rear springs? The car has front and rear sway bars, Bilsteins and monoball
front mounts. (IMG:style_emoticons/default/beer3.gif) (IMG:style_emoticons/default/smash.gif) |

Excessive scrub radius......BTDT and pushed. No amount of suspension tuning will get it out but will increase oversteer on wide corners. It the tighter stuff...most autocross corners, you need so much steering lock that the tire actually gets out ahead of the ground/strut center interface making the tire shuffle sideways. I replaced my 10 inch wide fronts with 8 inchers ...a 1 inch reduction in scrub (no other changes except new tires for the wheels) and now the front end bites. There ya go, a freebie that took me over a year of misery to finger out.
The other solution is wheels with 1 inch more backspace.....which won't fit as the strut gets in the way. (IMG:style_emoticons/default/headbang.gif) |
