There isn’t half some crap being spouted on here.
MK1s DO NOT have coilovers (when we’re talking coilovers, I mean adjustable ones) as standard. As someone mentioned above, some models came with Bilsteins (S-Special maybe, V-Special maybe and probably the RS) which if not looked after, will be really baggy by now.
I ran coilies on my first 5 and it handled waaaay better than the subsequent 2 I’ve owned. Was lowered (quite a lot – an S-Special but it wasn’t on Bilsteins) but I preferred the drive to either of the others (the 3rd one was another S-Special but on stock suspension).
If it were me, I’d get on Nutz and ask on there as well as maybe contacting Performance5 and asking the guys there.
Can’t wait to get another one… and strap a supercharger to it.
