mik I have the LCAs from the rally car that had been lengthened. They were extended about 25mm with box section steel. I'd prefer to add a bit to them to strengthen them more (and make them look stock again) but it's worth a look. If you have time this weekend to come past, you are welcome to take a look and see what you think.

I don't want to drill x member, im running lower struts so rca may be of benefit but track increase would be to match the proposed increase in rear.

Roll centre adjusters will help with correcting short length strut assembles by increasing the overall strut assembly length and therefore retaining some angle back into the LCA. More or less, you want the LCA to be parallel to the road surface at full bump [at a maximum] otherwise you will gain positive camber as the LCA moves through the arc

Shorter strut assembly will also increase camber without increasing track width.. Be mindful moving the LCA pivot point [on the engine crossmember] as it can screw with your steering geomentry.

Primarily track benny. The camber could be good too depending how,much neg camber it gives me

Yes, longer control arms will increase track AND provide negative camber. It does both unless you modify the inner fastening points on the crossmember.

You can have a machinist fabricate the roll center adjusters.

What are you wanting to achieve as a result of longer LCA's. Are you wanting increased track or increased negative camber or both?.

Ok but where to get them as they look like they would increase track width too

The ones in the photo i believe are offset for the strut -- for negative camber.

Yes but I would like off set ones to space the strut sorry not the ball joint further out... That would increase track too
