Help with Alignment settings

[PrestonH22]

I have a 1971 914 with a built 2600cc engine. It has new bilstien struts up front with all 911 components and the 20mm underbody sway bar. The rear has new bilstien struts with adjustable perches and 200lb springs. Wheels are 16’s by 7 with 205 tires. What camber castor and toe would you recommend for a street setup. The car gets driven very hard but won’t see many miles per year.
Thanks

I have a similar setup and am about to set alignment within the week. Gotta get the ride height and desired rake first. I intend use standard 914 specs on aggressive end but maximize the front caster equal on both sides. This is the plan unless someone else chimes in here. This setup is for the street. For track use, totally different. I like toe out in the front, about 1/16" per side, measured at the outside rim. Rear toe in about the same amount. Probably maximize the camber on all 4 corners. Front caster to taste... I prefer less on the track.

Is it a little squirrely toed out in the front?

[roblav]

No, not squirrely, at least after the tires heat up. Front toe out helps turn-in.

I agree with roblav, but make it 1/8' instead of 1/16".

I have found that any appreciable toe-out in the front will make the car more squirrelly, requiring attention at all times to keep going where you want it to. Not bad in some circumstances, but not optimal for a street car that goes on long trips where your mind can wander. Furthermore, crisp turn-in is not critical for a street car.

Standard alignment specs should work pretty well for a street 914, even with a large motor. That would be on the order of 0 to 0.5 degrees negative camber all the way around, about 6 degrees caster angle in the front, and a little toe-in at all four corners. Use the camber to tune the handling for oversteer/understeer, and tire pressures to make finer adjustments. Or if you're not interested in going through that, set it at 0 degrees camber at the front and 0.5 negative in the rear.

Correction, I have 1/8" per side front and back, but toe-in in front and tow out at the back.

I would never run toe out in the rear......for street go with standard toe in (front) and toe in (rear). If you auto-cross just take two open end wrenchs and turn driver side tie rod two turns which gives you a strong 1/8 toe out in front. Great for auto-cross turn in, after timed runs just turn tie- rod two turns back....off you go. Did this for twenty years. Best, Mark
