Having finally got my SLK280 back and starting to enjoy driving it, I (and SWMBO in the passenger seat) find the ride a bit harsh. ATM she's on a staggered set of Hankook Ventus tyres, 245/40 on the rear and 225/45 on the front (soon to need replacing due to outer edge wear and buggered tracking, now fixed). Interestingly, the original road tests of the R171 on 17's commented on the harsh ride and suggested it would be better on the standard 16's rather than the optional (as fitted to the test car) 17's. I obviously have 2 options : 1. The cheap and easy option is to change the Hankooks to something better, based on experience with my S204 and previous 968 cab I'd lean towards Goodyear Efficientgrip Performance for the fronts and Eagle F1 Assymetric 3's for the rears. Cost to change all 4 about £4-500. 2. Change to 16" rims and new tyres. Brand new I'd be looking at about £1100 minus what I could get selling the 17's, and even looking on eBay I would not do much better buying a second hand set, getting them refurbed and installing new tyres. Would appreciate thoughts and experiences from other owners of R171FL cars. Having converted my S204 from 16's and Contisports to 17's and Goodyears, transforming the ride and drive experience for the better, I'm not sure which is the better way forward!
