I have a pair of front and rear SS bars that I don't need. Sway bars have actually been cheap to ship in the past.
You suspect?I don't know that. I suspect one would be hard pressed to tell the difference.
Bolt up a Hotchkis bar if you want a noticable difference.
The R1P cars have the SS/9C1 sway bars.My experience with two FWBs has been that the oem (FE1) rear bar is appreciably visibly really smaller dia. than the SS bar. On my first one I replaced the oem front with the SS front from my SS (which itself then got an F-body bar), and then replaced the stock rear (the notably skinnier one) with the SS'es rear bar (which then itself got an HO rear). I then 'added' the FWB rear bar back onto the SS rear bar for no less understeer than without it (still shoved in corners even with 255/50-17 - Bilstien - old sacked out SS coils) So, I then got another SS bar from a friend and doubled them up back there. Now THAT ran it much flatter = very nice. And yes, more oversteer.
For my current FWB I got an SS bar for the front and took the second rear SS bar off the other FWB for the back as I don't need the current driver quite as road-hugging. There's another FWB regular on here who saw about my doubles and decided to just combine the oem rear bar with an SS bar and he's pleased. Just a bunch of reference FWIW.
Uh...Thoiught you meant "RIP" package ,not R1P.... Assuming hearses= RIP.......
