hi there, if you are serious about putting a sr20 into it in a few years, ive heard that silvia s13 front suspension will bolt straight in, if this is correct, you can use the silvia brakes, which should pass engineers when you have the sr20, as the sr20 came in the s13. do sum more research, cause i know there are heaps of upgrades for s13's, which will fit onto the s13 frontend. :)
