Alignment massively out of whack after track day.

[Mike B]

I had the car put to OEM alignment just before Marham, half way though the day the straight line stability started to get pretty bad.

Heckler and I were hammering up the runway at around *ahem* 160+ and the back end was dancing in tiny increments left and right. The rest of the circuit is spent balancing on one wheel so this is the only place you could notice...

All the way home I could feel the same thing intermittently.. so I got the car cecked this morning and front and back camber and toe... all out!

We tightened it all up well.. I watched the tech guy do it..

The last silver sup I had.. again got the geometry done, did brunters, everything fine, then handling went to hell, and then... no rubber on the inside of the tyres...

so the moral of the story is get your geometry done twice a year if you want to get the best from your car, and tyres for that matter!

I had been reading through the forum on all the geomerty posts I could, then spent a couple of hours on http://wheels-inmotion.co.uk/ and went today with the aim of taking as much of the rear camber out as I could, as I use 19's. I cannot reduce it to less than -1.5 on the back... you can see the camber in the wheel - no wonder the inside edges run out on 19 rears.

I may try to see if I can get some different cams, and wonder if you can get adjustable arms?

either that or I should go 18.

either way the concencous seems to be that it's a black art.. not one setup goes on every car.. by any means.. it's a pro's job on each and every car..

so I feel a trip to CW coming on.

PHR do adjustable arms +/-10degrees! a good buy for peeps with 19".
Get in touch with Terry, he knows the chap does the Ferrari 355 cup cars geometry, and is a master of getting it right. With your setup text book setting will be pretty useless.

CW will prob chase you with 19's

MVP do camber adjusting bushes, they aren't too expensive, but you need some professional stuff to get them in and out easily.

Thanks for that I'll have a look...

I'm aware Chris has a sign on his gate;

"beware the dogs; no canvessing and no 19 inch wheels"

I have one bush that is ceased at the moment, the cam is locked into the rubber. I managed to strip all front bushes out of my old car's front suspension using a big vice, different sized sockets and an uncle called "keith".

all I can say is I'm glad Keith is my uncle! I think his middle name is brick top.

I could do with a shopping list from Chris, or perhaps I'll get hit with the 18 inch stick instead. Either way he's a lot closer than the south so I'll probably end up there.

Mike, As you saw at marham I'm also on 19's and I believe you commented at the time that I had pretty good tyre wear. I just dug out my last Geo printout and it is as follows:

Rear axle. Camber -1.5, Toe + 0.27

I realise every car is different but thought it might help. I have used this with both 265 30 19 and 275 30 19 and at the most the wear is about 0.5mm different from inside to outside edge.

I haven't managed to sort the front out yet though, I get bad wear on the nearside inside edge but I'm pretty sure its due to a little 'play' I just found in the wheel bearing.

Thanks Matey,

I have a stuck adjuster at the moment, so drivers side is -2.0.. the other side is -1.5 but that is as close to neutral as it will go. Those rear F1's are starting to get a healthy lean on them.

The last 2 sups I had were running 275's, this one has rolled arches so I can get 295 in there, but with such small tyre walls the extra camber is really loading up the edges... I wonder if allignment ranges are different from car to car...?

Marham really tore up the tyres, but with the quality of grip and tomfoolery that ensued it's not surprising.

Memory has kicked in, mine went out once not long after getting it set, second time I insisted on the torque wrench @ toyota specs, didnt move ever again.
