Dear forum members I wish to say how much I enjoy reading the posts and photos, some of the restoration projects are mind blowing.
Here is my question I have fitted new top and bottom ball joints to the front suspension and also fitted an EZ electric power steering unit (what an improvement in the drive ability of the car) any suggestions as to wheel alignment settings or do I stick with the standard factory settings. The car is a 1964 V8 saloon driven on club outings at just below highway speeds.
Suggestions appreciated.

I suggest you watch TJ's thread as it progresses to Ackerman steering and angles. Standard Jag set up is inherently zero castor or camber & 1/8th inch toe in. Strange by modern standards where negative camber (up to 3 deg) and high castor angles are the norm (+- 10 deg).

Your problem with R&P steering conversion is likely to be not maintaining Ackerman angles & suffering front tyre slip & scuff.

You might have to experiment with slight toe out to even out front tyre wear with R&P.

 

Hi Glen,
Thanks for your quick reply.
My power steering is mounted up under the dash panel and drives the normal steering box so the steering is as it came from the factory.
My shop manual lists camber at 3/4 deg. +or- 1/4 deg pos. castor 0 deg + or - 1/4 deg toe in 1/8 ".
Would you stick with the factory settings or run a bit less camber say 0 deg castor a bit positive and 0 toe?
Your thoughts would be appreciated.
Regards,
David B.

 

Sorry ~ misunderstood. Thought you had fitted electric rack & pinion.

Just stick to factory standard. Without major modification they can't really be improved. The small range of tolerances they show are not going to make any difference to anything. Keeping tyre pressures right will make more difference.

The Mk2/S Type front suspension & steering was designed before the days of anti dive considerations & high speed straight line stability with strong self centering.
