1973 911 set up
Discussion
I was hoping to ask if anyone had any advice on the suspension set up for a car. It’s a 1973 T that’s had a full nut and bolt restoration. Luckily it had the magnesium engine case and so it could be rebuilt to 2.7RS spec.
The use will be summer in the UK and trips to the alps. It’s already been over once and performed well. The front tyres have had some uneven wear and it’d be useful for some advice on the initial set up settings and then it can be refined further. A local guy who regularly sets up Ford Escorts for racing will do the job initially. Although very respectful of centre gravity and their work, I think it’s reasonable to do an initial set up and then review the response.

Car looks lovely. So you’ve got a 2.7 RS engine in your “T” ?! That’ll be a lot of fun. Who restored it for you ?
Car looks to have a lot of rake on it ? Seems like there is a fair gap between the rear wheel and the arch ?
Can’t really help on the set up as I am clueless about these things other than I took my ‘73 911 for a suspension set up to CG a few months after I bought it. Transformed the car. The car had previously had a suspension set up by a Porsche specialist who people speak of very highly on here. My car had too much rake and had been set up with too much rear toe and didn’t have enough compliance. That meant the rear wheels were fighting the front in corners and meant the steering was heavy. I clearly didn’t realise this until CG had worked their magic….

Nice car
I had my suspension (1972 911T) completely refreshed, upgraded including polybushed and set up all by Tuthill a couple of years ago. Highly recommended.
Many Ts of that era (like mine) did not come with rear anti-roll bar (ARB) and would therefore need brackets welding on, while the front comes with the fittings so the ARB can bolt on.
There are very few companies I would have weld the brackets in place for the rear. Tuthill are excellent and know these early cars inside out.
Good luck.

Best start from factory settings for these early cars,rake should be 1 to 1.5 deg,you need rear toe in which wont fight the front wheels,toe out is scary on the rear.1 mm of toe in on the front,depending on the tyres used what grip they generate on the car will highlight the flex in the car,standard tyres the car will be fine.
You dont give much info on new dampers/torsion bars/bushes,has it been on a jig etc.
Half tank of fuel always helps,enjoy great cars.

I’ll send a PM regarding the settings if you don’t mind.
