That's some serious rear rubber! How do you find the SportMaxx? Only ever had PilotSport 3 and PilotSuperSports
Only ever done these on a Bora, so by no means an apples-to-apples example, but there was certainly extra 'crispness' and precision after, and no decernable increase in firmness, so I'd say go for it!
The unknown issue with the Dunlops when I changed to them in Dec 2007 was the wear and longevity, as they were only just out then and I was one of the first to put them on an XK.
Well, they're still on there after almost 7 years (yes, I know I should be replacing them!) and 24,000 miles but the rears still have 3+mm and the fronts 4mm. I have them aligned twice a year, though - not cheap as it's 4-wheel jobbie - and keep the pressures right and it certainly seems to be worth it.
It also stopped the tramlining I got with the Pirellis and others have reported that, too.
Back to our CLs ....... mine has several small areas of "rust" where I presume the aluminium has reacted with the steel - does yours have any? I'm going to have to have this done and have read that, if done properly it doesn't come back ........ do you know?
Cheers,
Stuart
