Hello 914World.
I recently purchased a '74 914 racer and had it on track at Buttonwillow raceway last weekend. There were issues in that the car was last raced in 2014 but these were overcome.

Here is the major problem with the car. Body roll. Transitioning from a right to left turn requires neutralizing the car mid cormer and then allowing it to set. If that isn't done, the car wants to break loose when it sets into the next turn. I don't have a rear sway bar on the car and that is the first order of business but it seems impossible to me that a sway bar could overcome this much roll by itself.

I was thinking of trying coilover shocks to help with this. This might also allow us to corner weight the car.

What are your thoughts on this. Any other strategies that have worked for others with 914 racers?

I appreciate your input. Bill Pierce

I run an aftermarket (larger diameter) rear bar with adjustable drop links
Really like it although I don’t run it very tight

The problem becomes the need for a limited slip

I Like street cars with stock bars also

But driver style probably plays a role in rear bar applications

I have the information many have requested.
The car has:
Turbo tie rods
23 mm front torsion bars
Bilstein shocks/ struts with 225 lb. rear springs
19mm front sway bar
Purchased, but not installed 16mm Weltmeister sway bar
Toyo R888r tires

I have heard the concern about the need for a limited slip diff with the addition of the rear sway bar but hopefully I won't unload a corner sufficiently to lose traction

Any other advice? Thanks, everybody. Bill Pierce
