mishmosh Posted May 10, 2015 Report Share Posted May 10, 2015 My GT4s has always been a bit lairy on corners ( as experienced at Donington last yr! ) I know the chassis has its inherited failings, but my 1200 corners so much better. Armed with some shims I decided to check the rear tracking. I laid a 10 ft length of timber alongside the tyres , propped up 6 inches , and measured. The wheels are within 2 to 3 mm parallel . I then slid the timber forward alongside the front wheels. On the n/s it remained reasonably parallel to the rear. On the O/S it showed around 12mm gap at the front of the rear tyre. Now I always assumed the wheels were in line! I guess one of my driveshafts is shorter? Or? ideas ..... Link to comment Share on other sites More sharing options...
PeterH Posted May 10, 2015 Report Share Posted May 10, 2015 I've been meaning to post on a similar subject. Over the winter I fitted a new rear spring to my Mk3 Spit. I've now got excessive (over 3 deg : max reading on Gunson gauge) camber on the nearside wheel. Perhaps one of our experts can help us both.

Pete Lewis Posted May 10, 2015 Report Share Posted May 10, 2015 did you load the car with rent a crowd on each seat ? or have you got the unladen spec ?? all you can do at the back is get the toe near '0' Laden and even up the alignment down each side to be equal which may need a different shim count left to right . as for camber ......one old favourite is drive shafts intermixed one is around 1/2 longer on later spits they get mixed around over the years quick look with a tape measure over the shaft you can see will tell you. tight trunion bushes, off centre spring eye's ...diff mounts . ..... is there any 'lean' Pete Link to comment Share on other sites More sharing options...
mishmosh Posted May 10, 2015 Author Report Share Posted May 10, 2015 I have no specs to work to. Tried unladen. Its the off centre that puzzles me. No lean. Will measure shafts. Thanks. Link to comment Share on other sites More sharing options...
PeterH Posted May 10, 2015 Report Share Posted May 10, 2015 My drive-shafts check out. One day when I've nothing better to do I'll turn the spring round and see the camber angle changes side. Link to comment Share on other sites More sharing options...
Clive Posted May 10, 2015 Report Share Posted May 10, 2015 Sounds like the rear wheel are not parallel to the centre line of the car. You may need to tweek both rear wheels so you end up with an equal gap, if that makes sense. I have just checked and the track width is the same on herald based cars. Odd one is late spit 1500 and GT6 with long shafts. Link to comment Share on other sites More sharing options...
