he recamends cutting about a 1/2 inch off stock bump stops in the rear (at least for my coupe)
or, order there shorter bumpstops (p# BS 45001617) (included with the lower Sportline kit)
I have a gt coupe w/ eibachs & (my right rear bump stop has about 1/2 inch cleareance) my dad has a gt vert, I just ordered Vert spec coils for him and the shorter stops
When I got mine for my 99 GT the shorter ones were included. I ordered mine for my 05 direct from Eibach, and although not included, they 'strongly' recomended getting them. Glad I did. I intend to DRIVE this new baby. It's short $$$. Get them!!
