j_jza80 Posted February 3, 2017 Share Posted February 3, 2017 Edit: It's also worth noting that I've gone for a larger profile on my tyres at the same time I swapped the suspension, which probably had a lot to do with it. That explains a lot I've just gone from 255/35 rears to 275/40 (or 265, can't remember off the top of my head) and there's a noticeable improvement.

Dnk Posted February 3, 2017 Share Posted February 3, 2017 (edited) That explains a lot I've just gone from 255/35 rears to 275/40 (or 265, can't remember off the top of my head) and there's a noticeable improvement. Thats 16mm more sidewall height so will change the ride massively, and thats on 265/40 My car from stock lost 13mm of sidewall height but never felt too harsh to drive on the road, it wasn't a daily though so didn't have to suffer poor road surfaces very often Edited February 3, 2017 by Dnk (see edit history) Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 3, 2017 Share Posted February 3, 2017 It was a great upgrade, the only thing I haven't checked is how it's affected the Speedo. A session with the sat nav is in order I think Quote Link to comment Share on other sites More sharing options...
samdale Posted February 3, 2017 Share Posted February 3, 2017 Spring rate is spring rate, Chrome Moly steel, Ti, plastic, wood, rate's rate. So all springs (of equal rate) are equal then? Quote Link to comment Share on other sites More sharing options...

marc_p Posted February 3, 2017 Share Posted February 3, 2017 Tein's are fine in my opinion, just don't go for there budget options, a set of Flex's with an EDFC controller is a good set-up in my opinion, it's not crashy and they soak up the bumps well, then with a quick push of a button they firm up nicely for those rare times when you find a smooth road.

Dnk Posted February 3, 2017 Share Posted February 3, 2017 No, I'm on 18s just double checked and they're definitely a 275/40/18 on a 9.5j wheel. Around 6% over OE Speedo reading 50 actual 53 http://www.tyresizecalculator.com/tyre-wheel-calculators/speedo-error-calculator Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted February 3, 2017 Share Posted February 3, 2017 Cheers dunk Considering they over read as standard, I'm guessing that the Speedo is probably more accurate now at motorway speeds. Quote Link to comment Share on other sites More sharing options...
