Hello 914 Racing experts:
I've had the same suspension setup for many years and would like to upgrade to reduce body roll and improve rotation capability of the car at turn in. Car is used primarily for PCA track days. Here is my current set up: Full welded cage tied into rear shock towers 16 X 7 front 225/45 Toyo 888R 16 X 8 Rear 245/45 Toyo 888R 23 mm front torsion bars 180lb progressive rear springs Bilstein shocks front and rear Weltmeister chassis stiffening kit boxed rear trailing arms Delrin rear suspension bushings Rubber front bushings turbo tie rods Engine: Raby 2270 180hp Upgrade Plan: Install 19mm (smaller size) Tarett Front Sway bar Install Tarett front bushing kit upgrade rears springs to 250 lb. with Tarett coil over kit install Tarett front monoballs Maintain current shocks even though 30 years old What do you guys think? Car has great grip currently and is a lot of fun to drive. |

If you are running a limited slip, my 1st upgrade would be a rear sway bar, and see what that does. I'd go with one thing at a time and see if it's to your liking.

QUOTE(Perry Kiehl @ Jun 13 2018, 03:13 PM)  If you are running a limited slip, my 1st upgrade would be a rear sway bar, and see what that does. I'd go with one thing at a time and see if it's to your liking. i currently have no front or rear sway bar. My thinking is I have stiff front torsion bars so I could go with the smaller size tarett front sway bar then increase rear spring rate to match increased roll stiffness up front. |
