Right, my first question to answer is one I should have answered yesterday, but like an idiot, I forgot! Are the tyres XL? Yes
So this morning, I've had her up on ramps, removed the three bolts on the plate, and slackened off the main 17mm bolt. I've then torqued everything back up to spec. The difference this time, is I did it with the suspension loaded up, rather than on an axle stand on a non-moving component. I was wondering whether having the suspension hanging slack may have put things back in a slightly different place. Who knows? At this point, I'm fishing!
Been out for a test drive, and it still feels a bit odd......but not as bad as last time I drove her. I'm suspecting it could be the tyres, as it feels better in the mornings (my morning commute is generally 5am), than it does in the evenings, when everything's baking hot. Maybe the Rainsport 3's just aren't up for ordinary worn crappy tarmac that's really hot.
My test route took in a long sweeping left on the exit of a village just down from mine. The corner is beautifully surfaced with some of that evil yellow supergrip stuff, and the car felt good around it, with none of the oversteer/understeer/oversteer random factor that I've been dealing with lately.
So, weather suddenly gets hot this week, coinciding with me screwing around under the car. It could just be a perfect storm of coincidence!
I'm gonna wait until it cools down a bit, and see if anything feels different. If it does, I'll be here asking for recommendations on really grippy tyres.........and sending my R3's to ebay at a 50% loss :/
