johnny_52 Posted January 10, 2011 Report Share Posted January 10, 2011 Bout ye, I have a 07' Mk3 Mx5 Sport on 17"wheels. I have fitted Eibach 45mm lowering springs. The car is handling better but not as nice as i would like. I have booked it in with my local tyre fitter / mechanic. Have you got any figures or setup tips I could pass on? I would bring the car to WIM, but im in Belfast Any help would be appreciated Johnny Quote Link to comment Share on other sites More sharing options...

Tony Posted January 10, 2011 Report Share Posted January 10, 2011 -45mm is very low for a mk3 so my only concern is the lower control arms are going to be perpendicular and this messes with the roll centres. In addition i have no idea what the coil rates are, i assume nothing to aggressive since they have to work with the Billie dampers. I would look for a calibration like this ( decimal degrees ) Rear Camber: -1 degree 50' Toe: +30' total Front Camber: -50' Castor: +6 degrees Toe: +8' total Be warned the front anti-roll bar drop links are going to brake, in this event we do rose jointed alloy links as a upgrade.

johnny_52 Posted January 15, 2011 Author Report Share Posted January 15, 2011 have had the geo done, it now seems to handle alot better I have noticed that it seems to bottom out at the back, at speed over bumps, any ideas how to fix? It seems i may need to invest in better shocks johnny Quote Link to comment Share on other sites More sharing options...
