Its mentioned on here that having a proffesional outfit do a proper alignment, setup and spring rates is the best way. Good you have it sorted now.

Further transformed after a professional setup today.
Used a firm in Colchester that specialise in track hardware - mostly drifting.
The biggest change is in tyre pressure up to 28 front 30 rear from 22 all round. Castor wound back to 4 degrees, 1.5 deg camber on front, .7 on rear, and parallel toe rear and 2 deg toe out front.
Was a bit mystified until I drove it and found it delightful (not a delightful handful). We will have to see. The overall comment was nothing much is going to remove the twitchiness until I source different tyres as the super soft TB15's will always tramline due to their stickiness......
So I gave him the task of finding a set of matching tyres (there aren't any other than the Pirelli equivalents are there??)....

hope you've got good insurance.......
Tim, those tyre pressures sound way too high to me. Keep an eye out for uneven tread wear, especially in the centre sections! How does the steering self centering feel?
They're not trying to get you out there drifting are they?
Guy I was surprised too but after a long discussion I thought it could be worth a try. If they get work then they will heat up and pressure will go up but on the road they will not get this work as evidenced on my return the fronts were stone cold. I have to say the ride and steering feel was better.... No I am going drifting either.... If the tyres heat up then drop some pressure...., but the self-centering is compromised by the wider than spec super sticky "race" tyre. I will look out for uneven wear though as there isnt much tread to play with to begin with! Shame Friday looks quite wet as it is my travelling day to Goodwood and I doubt I will go in Shades after my boating experience this morning!Originally Posted by Guy Mayers
BTW what is the mph / 1000 suppose to be for a 164 12v fifth gear re tyre diametre as is seemed high c 27mph/1000?

Can't help with that Tim but suggest you try it with a Sat Nav that shows your speed? It'll give you a good idea how accurate it is. I've just had my speedo recalibrate by Speedy Cables as it was reading a tad too fast (approx 4 times I think!) but now it's spot on to the Satellite Speedo I bought to keep the "right" side of the law.

Hi Guy
Speedo already checked and surprisingly accurate! Not sure about the rev counter though which is why I asked?
Any idea of final drive ration in a std 12v box and 5 ratio (is it 1:1 or an "overdrive"?)? I can work out from first principles then...
Been a long day Tim..... Sorry, I don't know what the final drive ratio for a 12v box is.. The info must be out there on the inter web somewhere?

from the old forum
Brilliant. I calculated 20mph/1000 in 4th while on the move so that is spot on. Will do a more exhaustive test in coming days....
