Default 07 STi rear subframe and front crossmember into a GC - Help

l'm installing a 2006/2007 sti front crossmember, rack, alloy arms etc and rear subframe/diff cradle into my v5 sti

what rear lateral links would l use to match the increased track at the front?
(currently have GC8 STi pink lateral links (405mm hole to hole for each link)

and are there any other items besides the front exhaust hanger and unijoint on the rack that l will need to change to get everything working?

Thanks

a friend of mine has the rear lateral links off a GDB on his GC8, they appear to have widened the track a little bit.

l'm probably gonna sell the STi pinks and replace them with whiteline or cusco adjustable lateral links later down the track

l'm just wondering if the pink gc8 lateral links would be ok with the 07 sti control arms

The GD body style definitely has a wider track than the GC, but I don't remember what the difference in lateral link length (say that three times fast! ) is. I want to say the newer ones are 420mm vice 405mm. I think it's something in that ballpark.

I could go and measure the track car but I don't recall it being that much. I don't have camber plates in the rear and with the GD pink laterals I have -3.5deg. My guess is 415mm.

i guess it all depends on if you want the wider rear track, as there are ways to correct the camber

everything else you listed looks great, its just the rear lateral link choice and your steering rack joint that need to be dealt with

cool thanks for the info, l'll probably go for whiteline or cusco adjustable GDB 02-04 lateral links to match the track at the front

what about my 05+ GDB suspension, l've been doing abit of searching and read that GDB ride height might not work with a GC8 chassis
