I have just fitted Eibach springs and Bilstien shocks,the ride is a lot better than FE3,it’s not as jiggly,it’s nice and firm not harsh,the front as you know need a specially modified std shock housing,you can trade yours in for modified ones,they need a collar welded at the top of the strut to accept the Bilstien screw in collar,Konis are the same,after fitting and running around from centre of wheel to guard lip in measured out at 175,the back ones are a straight fit and the shocks have three grooves with a circlip that you can change the rear height,I set mine in the middle and centre to guard was 160 so to low for me so yesterday I compressed the springs and put the circlip on top groove and it came out at 180 with no fuel,shall fuel up during the week and see what the final figure is.Im passed cars scraping the ground so now I like them just nice and lower all round and no longer do speed humps terrifie me.
