Currently sitting on 215/35r18's (18x9" +30) due to clearance issues with the front coilovers. With the 5 lug swap, properly backspaced wheels will be on the agenda (18x9" +0ish 275/40r18 perhaps?). Regardless, I'm asking what YOU guys like, not what I should get. Do y'all prefer the shorter gearing for the canyon twisties or the longer gearing for the highway cruising? This was the real reason for the poll...
I am happy enough with the 3.55's in my car but at 70 mph I am at 2546 RPM with 235/50R17 tires from my calculator I made.
Online it says your tires are 23.9" in diameter so at 70 mph you should be around 2800 RPM or maybe my spreadsheet needs adjustments. Or you already have 3.75 gears that puts you at 2954 RPM. IMO, I think it would be worth double checking if my spreadsheet concurs with others. If my calculation does maybe you should inspect the rear end in your car to see what is in there?
Beau, hope you & your circle of family have a quick recovery. We have friends who have gotten it a 2nd time with the 2nd time around worst than the first.
I have the Moog CC821 rear coil springs on CHE adjustable lower control arms. The CC821 are progressive springs that are shorter than the stock springs but when combined with the CHE adjustable control arms it raised my rear end 1/4" at the lowest settings. I am happy with the spring rated the progressive use and very happy with the rear control arms. Made it a completely different car to drive compared to my worn out bushings and stock arms........just in case you want to spend more money.
I am not sure the difference in the spring rate between the CC821 and CC823.
Looking at where it broke it must have been cracked for a while from the rust there. I will definitely take a closer look at mine after seeing this. Thanks!
