Idealy you want spring compressors but...
Decient set of spanners err 25 thorth bit and a bit of time say 2 hours.
I think you can just about get the strut tops on without compressing the spring ? Not ideal really but it should work.
For the sake of possible injury i'd drop a tenner on some spring compressors.
Bit of a thread hijack but edde, i've been looking at apex kit i've got ordered and the picture on k-tec (http://www.k-tecracing.com/show_product.asp?id=1791) shows them without the front springs on the dampers. Have I got to use the strut tops from the standard suspension with them or have the tops been removed in the pic ?
