I know there are a few of us with v8 powered 914 racers so I will put this to you for any info you may be able to help me with. With my first test sessions, I felt as if the rear of the car wanted to come around on light throttle through transition in corners. I have toe in on the rear and toe out (1mm total) on the front. Great turn in. My track was 90 mm wider at the front than the rear so thinking this was contributing, I modified the front suspension today to narrow the front track and are now sitting 30mm narrower at the front than the rear. I'd be interested to hear from others as to their set-ups. ( if its a real secret you can PM me haha. Any help from guys with a similar setup would be appreciated

Veekry9;The inner console does have doublers as well as the outer console and the shock towers.
It is running a Suretrac Helical diff. these are a tourqe biasing diff( not sure of the load required to lock up though. The engine is an LS1, pretty much standard except for fuel system upgrade, running stand alone computer, 7lbs boost, 520hp at the wheels, using an accusump to protect the engine. I have done the youtube thing but not on the chassis as yet. Racer Chris; haha. the good thing about narrowing the front is that now it will fit on my trailer easier Rich, ARB = anti roll bar. I have a blade adjustable bar at the front and a hole adjustable bar at the rear. spring rates are 6kg/mm and 8kg/mm Mike; I'm not running spacers, I installed mcphearson struts from a Nissan sylvia. Anyway the front turned in well, Everything I've done to the front end will have altered the scrub radius, but this would'nt affect the rear to any degree. Chris P.; problem only on trailing throttle midway through the corner. Drivability; with your setup you can at least get info straight from the spec boxter crowd or the cup car teams (IMG:style_emoticons/default/w00t.gif) |

QUOTE(returf @ Jan 11 2015, 03:41 AM)  ... spring rates are 6kg/mm and 8kg/mm ... That's roughly 325 lb/in and 440 lb/in. Have you calculated the wheel rates? McPherson strut wheel rate is lower than the spring rate; trailing arm wheel rate is higher than the spring rate. Therefore, on a 914, the higher rate spring is at the front. |
