Hell, buy the time you buy those adapters at 170 and find an MR suspension, you'll have just spent what a coilover set would cost. What's the point then?
Cost me 20 bucks to have my bushings welded in. $150 for the non MR suspension, plus $210 for the Tein front upper plates. I spent $400 on my swap with all new oem bolts.
I also recommend running uncut front evo bumpstops, as without them my car rode rough as hell, with them it rides way better. More predictable handling too. Use brand new ones for the best feel. They are only around $20 each from the dealer.
