Just a quickie. If the tracking is absoltuely spot on but the steering wheel has slightly more (15 degrees) lock on one side to the other, will there be any side effects, other than unequal lock?

And, does everyone elses 993TT follow the road camber has keenly as my car. At low speeds the car often wants to go up the path. Maybe my local council spend less money on the roads than others?

I think brand of tyre and amount of tyre wear is a big factor in this.

Yes and I just had and alignment done (still the same), I find my self wrestling the car at times.

It eases my mind that my car isn’t the only one

(BTW ace you didnt answer my email :P)

It means that (probably successive) front toe adjustments have been done on one side, then the steering wheel has been refitted a spline out to compensate ... or one of the other possible combinations influencing this. The only other outcome might be different amounts of bump steer side to side, if one tie rod is significantly longer than the other.

My S on 18s does not have a problem with road camber so much as seams in the asphalt and ruts as found on the slow lane of all Mways ....

cheers, Maurice

Sorry SMTK,

Book through RMA - only £120 - Bargain!

I used a snap on tool reader.

Maurice, this is exactly what's happened. The wheel was 'right hand down', so i turned it one spline but that sent it too far. I then tracked it up myself but forgot to put the wheel back a spline first!
Just wondered if there would be any other likely side effects than just excess/lack of lock?

probably need to check that 'they' have fitted it properly, which is a bit of an issue of late !

But how can you check?

I'm thinking spirit level, protractor and a plum line

a) are you running same tyres all four wheels; condition? age? (The tyres, not you! )
b) try steering from dead centre to left, then dead centre to right -is it the same? If not -see c)
c) take it back and get 'em to do the job properly!!

I would say C. Easier (slightly) going left than right, but, this is the third time the alignment has been done, first by OPC, then Parr and now AMD.
It has ALWAYS been more keen to go left than right which I put down to road camber.
I've always ended up setting the front tracking myself, usually by using chassis reference points rather than the rear wheels as most do.

still trying with "Garage X" after they finally admitted not quite fitting it properly and with parts that didn't quite fit in the 1st place !

Well, I was sceptical of their abilities but to be honest they were 95% excellent. I've now re-aligned my front end (about 6 times today) and the proof will be in the amount of time I spend on the grass tomorrow at bedford!

Regarding tracking and following the road camber in my 993TT, its a lot better than with my 964 on exactly the same .
ps and is always roadsto the left when it has happened

Well, for those interested in upgrading 993 suspension, I'd say go for it. PSS9, lowered about 15mm, wound up to hardest setting on track with 1.25 neg camber on front and 1.7 or so on the back, near zero toe in all makes for a very nice handling car on track.
On the road, the sorftest setting still provides a better ride than the standard worn shocks.

New setup is much easier on the tyres and driver alike.
I did a total of 155 miles around bedford all without feeling fatigued, unlike I usually am after wrestling the car around for just ten minutes.

Much fun was to be had with both Porsche4life (thanks for waiting) and 993Ken. Only 2 trips to the grass the whole day!

Yep, can confirm that your new chassis set up enables you to pull previously un-heard on angles in a 993TT, was jealous how much fun you were having..

Anyway had to retire - had sudden (and i mean no friggin warning what so ever) brake failure into one of the hairpins, just managed to miss the car ahead and went straight on into the marshalls hidy area.

Putting it down to losing one front duct earlier and must have some moisture in the fluid....

Anyway.... job done... rear tyres shot... new tyres on order.

Great day...

Sorry I had to shoot off so quickly Porsche4life (I make say that a lot ). I meant to come back and say bye but could see you still going round!

I'm back up there on the 14th of January, booked directly through motorsportvision.co.uk

My 993 C2 was particularly bad at following cambers - both before, and after I fitted the M030 and HD shocks kit. Probably worse afterwards to tell the truth. My 993TT is better, but I still find myself wrestling the car sometimes. The car has brand new P-Zero's all round.

As has been said a few times before, it is a lot worse if you tighten your grip on the steering and start getting tense in the shoulders / arms. Seems to really fidget all over the place then. Am getting a full four wheel alignment check done at JZM in Jan, but to be honest don't think it will make much difference as a brand new suspension setup and alignment from GT-One on the C2 didn't help matters any.

Got to say that by comparison the F355 was well and truly planted at any speed, never struggled with the steering wheel or felt the car wanting to wander.
