    Live rear axle longitudinal watts linkage

    Greg I think your thoughts about the elasticall bar can be quite right, it once bent slightly upon heavy contact. But I was able to finish the race. With a broken watts it was game over. Maybe the watts need to be of big dimensions on the axle bolt to whitstand impact better? But then the...

    Live rear axle longitudinal watts linkage

    My suggestion would be (similar to Norms) a 3-link with inclined lower links and a right offset upper link with a panhard bar as long and low you can make it. Volvo PV uses this layout. The inclined lower links will minimize roll steer. The upper offset link will minimize torque reaction on...

    Constrained testing in traction

    What offset do you think would be the right one? (the mount will then be adjustable 4" from that point). I have a packaging problem with the exhaustsystem which is around 4 inches to the right. It is possible to replace it with a smaller silencer. Do you need more dimensional information? If...

    Constrained testing in traction

    Thank you Joest for joining the discussion. Okay, I´m going with a 3-link setup were the lower outer links are almost horisontal maybe a bit angled up towards the front. The single upper link will be angled down about 10 dgr (to try to hit the no squat no rise line with the intersection...

    Constrained testing in traction

    It´s even worse the links are about 2" lower at the frame than the rear end, but parallel to each other.(compared to the floor) If my understanding is correct this generates pro squat? It´s the general idea that if a car squats a lot it is a fast starter among all other racers. Do you think 4...

    Constrained testing in traction

    Billy, the 4link is not with any bushings that can flex so the the links are parallel, because of the binding condition that come in play with non parallel links. All the links are uniballs(I think you call them rod ends) Therefore it would be better with a 3-link setup, where the binding never...

    Constrained testing in traction

    Hi Billy My name is Richard Malmlöf, i live in northern Sweden. I compete in something called "RallyCross". It´s an arenasport with gravel and asphalt, the course is 1km long and we drive for 3 laps clockwise. Its a standing start with 6 cars in a row(so the launch is crucial for the outcome)...
