your gonna spend alot for STi lateral links that only have better bushings and are just as big as your stock ones and not adjustable. I would sugggest getting 02-03 OBX adjustable lateral links. I just put them on my 93L and they are amazing. adjustable with pillowball mounts. and under 250 shipped on ebay. I got mine for 40 bucks at a local car show from a vendor that I know i got lucky...really lucky.
Yes you will, i have a slight rub on the left rear tire I think a fender rolling will help out though quite a bit. Im running 205/50/R17 for people that want to know and they are GC07 Prodrive rims if that helps with people wandering whether it will rub or not.
