So I have been on the RK Sport coilovers for about 3 years now, And decided to swap struts. Well I could not get the threaded part of the coilovers off the strut. After hammering for about a hour I gave up and ordered some sportlines. I did not install them in the first place, So I'm wondering what parts I will need to get the swap to work? I know the guy who installed the coilovers had to swap parts, My main question is in the upper part of the assembly. I'm sure that the coilover spring may be smaller then the sportline? Any help would be great! Thanks
