Maybe at least worth a phone call. http://www.centregravity.co.uk They are amazing for chassis setup (they did my cayman in March) but possibly overkill for this. A hunter roadforce balance really is the place to start. I'd bet money on it being a tyre out of balance Quote Link to comment Share on other sites More sharing options...

I'd bet money on it being a tyre out of balance I would like to agree with you thats its just a tyre out of balance, but the symptoms are identical even swapping to brand new tyres and 5 attempts at balancing accross 2 different tyre fitting places makes me think that's a heck of a coincidence. Even so, the place I'm going to take the car to tomorrow said it could still be the case. It will be interesting to find the root cause. I'm quite prepared to eat my (metaphorical) hat of course.

I went through very similar with my Cayman and in the end it was because the normal tyre fitters hadn't accounted for a stiffer part of the tyre. I had it roadforced balanced, the tyre rotated, and voila, all was well in the world. I think the issue is that Porsches (which have no weight over the front) are very sensitive to imbalances and so even a tiny error in the wheel balancing ends up causing an issue that can be felt through the wheel. You could of course have a more serious issue (buckled wheel, alignment problem etc) but it sounds unlikely to me... Quote Link to comment Share on other sites More sharing options...
andygo Posted April 27, 2021 Author Report Share Posted April 27, 2021 I looked for a Hunter roadforce operator not too far from MK but haven't been able to find one. Where did you find your place please? I guess I couod call Pro Align in Towcester who appear to be the `UK distributers. Quote Link to comment Share on other sites More sharing options...

It cost me 50 quid but was well worth it and cheaper than the 3 normal balances I had paid for Quote Link to comment Share on other sites More sharing options...
andygo Posted April 28, 2021 Author Report Share Posted April 28, 2021 Just got back from having my front wheels checked. Rims were absolutely spot on, nothing out of true. Tyres had a tiny amount of irregularity, but well within tolerances. Everything rebalanced, but they doubted they had fixed anything. Drove away and could tell it was better after about 100 yards, Went up the A5 and, er, pretended it was an Autobahn. All pretty perfect now. Pretty surprised it was all doen to balancing after all. Panic over, as you were. Thanks for the help, particularly PFX near Witney for his kind offer of a wheel swap. 2 Quote Link to comment Share on other sites More sharing options...

andygo Posted April 28, 2021 Author Report Share Posted April 28, 2021 Nope, its on 19" Sport Design 15 spoke wheels. They are pretty chunky wheels, so a fair amount of mass to have rotating when you think about it. Quote Link to comment Share on other sites More sharing options...

andygo Posted April 28, 2021 Author Report Share Posted April 28, 2021 (edited) I started to eat it, but got tyred. It tasted of hot air... I was a bit unbalanced when I suggested I ate that metaphorical hat, things are rolling along a little smoother for me now.

Ninesomething Posted April 28, 2021 Report Share Posted April 28, 2021 Guy that runs my local tyre dealership had a similar prob with his cayman. Tried everything including having the tyres shaved which I've heard done on race tyres but never road tyres. Nothing worked and he knows his stuff. In the end he put a pair of new tyres on - cured. He won't fit anything but PS4s onto my boxster because of this. That or he made the whole thing up to make me spend more money. Quote Link to comment Share on other sites More sharing options...

andygo Posted April 29, 2021 Author Report Share Posted April 29, 2021 That's nice of you. Do you think I can twist your arm and leave the brand new Michelin Pilot 4S's on? Such a faff to take them off and dump them. 1 Quote Link to comment Share on other sites More sharing options...

Fabulous, really happy for you - it's the type of problem which you just can't ignore and it gets you worried thus spoiling the experience....
