So, hit something in the road last night, took a three inch chunk out of my front tyre, air pissing out of it, now completely flat sitting on the rim. FFS!
So, two new front tyres it is then!! The current fronts are Goodyear's, I recently put some Bridgestones 050's on the rear. Should I get some to match the front's too or go with something else?
Car is within warranty currently so need to stay N-spec for now blah blah.
Michelin Super Sports - all round. So, two new front tyres it is then!! The current fronts are Goodyear's, I recently put some Bridgestones 050's on the rear. Should I get some to match the front's too or go with something else?

The bridgestone 050 are possible the worst tyre out of all of the N-spec crowd juding by most people's review of them. I have to admit I had them on my S3 a few years back and changed to Goodyears on that car and the improvement was vast.
I am not sure of my ride height, I can only just get over speed bumps with no scraping but if I so much as sneeze on the brake pedal before going over it will ground. I guess what I am interested to know is what the actual 'effect' is of increasing the camber up front, ie what should I notice, better turn in, more oversteer, and are there any downsides like instability on motorway, these kinds of things.

Have a look under the car at the angle of your lower control arm. The strut set up starts to get compromised pretty quickly as ride height reduces so try to be aware of the control arm angle versus ride height. You start losing camber gain rate once the arm goes past horizontal and the rate itself quickly becomes negative. fioran0 said:
The chalk is likely telling you more about the tire pressure at that time than anything I suspect. I would be wary of using it to provide much insight about alignment other than showing you have it set horrendously off.
I set pressures by temps across the tyre, on the track with only -1 camber you cannot go by temps as you are just over heating the outters.So 1st you have to fix camber to then allow you to look at pressures imo.
My pressure are about spot on with the R and even wear across the tyre for road use as you are not really over heating tyres on the road.
for a very close to stock my R is amazing with min money spent on it.
I will take any advice on how to set track tyre pressure though as I find this a battle on my Spyder, but again I am hoping with my new setup I might be able to now dial in the pressures better.

Can you get Super Sports in N-spec though??The bridgestone 050 are possible the worst tyre out of all of the N-spec crowd juding by most people's review of them. I have to admit I had them on my S3 a few years back and changed to Goodyears on that car and the improvement was vast.

I would leave the rear toe links unless your car is already lowered or your are intending to lower the car.
why ? it has nothing to do with ride height !I fitted rear toe links to mono ball to stop the rear bush's compressing and changing the direction of the rear wheel under hard braking.
I found the rear of the car squirm as standard and now it's brakes very direct and straight.

The fact that the fronts won't be N-rated would stop me putting them on my R, they are great tyres.
The Porsche warranty is only a problem if the unaproved tyres were the casue of the issue you were claiming under the warranty for, which is unlikely to be the case. I've never had a problem in the past with it.
As soon as my tread has gone past it's best i'm without a hesitation putting the PSS on mine, it's worth it for the difference.

I've got N-spec front and rear on my car, Bridgestone's at the rear & Goodyears at the front. I called Porsche Solihull and the service guy there said that it's unlikely, but it could be deemed an issue, that the brands don't match, even though both are N-spec. Therefore, I'm not putting non N-spec tyres on the front just yet, just not worth it at the moment.The Porsche warranty is only a problem if the unaproved tyres were the casue of the issue you were claiming under the warranty for, which is unlikely to be the case.

Once I've replaced the fronts, by the time the current set need replacing I'll probably be close to the warranty expiry so will have to make a decision as to whether I'm extending it or not.

I have not run N spec for years and have made claims, all be it a £65 clip and a exhaust bracket , it's crazy not to fit PSS. I would hate to run an N spec on any of my cars now.

However, if I have a warranty, there's no point needlessly potentially voiding it is there? No point giving Porsche an easy excuse to not pay out for something that they should do, just because I put non N-spec tyres on....

Have to agree - you could foresee that if you had any sort of handling/steering/suspension issue they could say (at least) that they weren't going to look at it until it had the recommended tyres.However, if I have a warranty, there's no point needlessly potentially voiding it is there?

Incidentally, as someone posted elsewhere, if you feel you need to replace both fronts because of there would be too much difference in tread depth between the new and old (but still good) tyre, it might be as well to keep the good tyre. Then if you have a puncture on the other side you will have a "spare". How likely that is on the front, I'm not sure - I once read that 80% of punctures occur on rear tyres.
