I know this has been covered before. Someone asked about 240Z track wheel alignment as they couldn't get their car to steer well. Lurch gave measurements of


Front Castor = 5deg positive - the more the better. (L&R)
Front Camber  = Start at 3.5 deg negative & adjust from there, via tyre temps (L&R)
Front Toe = 1 mm toe in (L&R)

Rear Camber = 2.4 (L&R) probably too much, but what are the tyre temps reading?
Rear Toe = 1 mm toe IN (L&R). Toe out makes IRS cars nervous in the rear.
 
According to the person asking for help this made a big improvement. Would this be the same for a road car or would I need something different? I recently went to get an alignment check and was told it couldn't be done because a 240Z wasn't on the computer data, as it was too old. I do have some old style alignment guys around but would like to have some specifications to take to them.

You will never get 3.5 neg camber with out adj arms.

That said it would be terrible on a daily driver too.

1 to 1.5 is plenty on a road car

0 to .5 on rear

Your front end alignment guy will only ever adjust the ft toe ( until you put adj castor rods, camber plates etc in)

 

Imm toe in is good for stability.

o or 1mm toe out helps turn in but the car can become darty at high speed.
