RSR Sway Bar Sizes
 

Can anyone tell me what sway bar sizes were used on the front and rear of the RSR monsters?

20mm front and 18mm rear was common in the early days, I think they got a bit bigger in 74.

Thanks. I just went to RSR valved and sprung coilovers. I also did a G50 conversion. I have had to go for a 20mm rear sway bar from a turbo (has a bend in it) to get it to clear the gearbox cross member. This means I have 20mm on the front and 20mm on the rear. I assume I should consider upping the front to 22mm to balance things out.

It depends. I have the 20/18 set up on my car. It's fine, but I actually would prefer a bit more oversteer than I have, so I'd actually be happier with the 20/20 set up you have now. Really a matter of personal taste so I'd try it for a few miles before changing. I'm not sure, but the G50 and your motor probably weigh a tad more than my closer-to-stock setup, and that would also affect handling a bit.

'73 RSR used 19/26mm t-bars w/ 22/26 option & 18/18mm adjustable sways, there were 2 optional sizes for the fronts but I can't find that info, wheels 9 & 11 x15 230/260 ires

'73 RS used 19/23mm t-bars, 15/16 w/ 18/18 option sways, 6 & 7 x15 wheels 185/215 tires

The 20/18 were used after the simplification which occured in '74 for most chassis('78 for 930)

The early front bars were through the chassis and adjustable, the simplified fronts are under the chassis and non adj.

Bill, which round are your numbers F/R or R/F?

always f/r

also keep in mind the cars weight when comparing these things, RSR raced @~2k#

thanks Bill.

I guess with the G50 on its a little heavier at the rear - so more like a late 3.2. However I have 7's and 9's on the car and RSR suspension. I may change the fronts to 8's soon.

Maybe the turbo 22/20 is right. I'll have to drive her to see.
