Wondering if someone could help me carry the anti-squat thinking some more. I mentioned earlier in this thread that we had problems with forward bite and that the rear would not take a set. One item that we found was that the pitch center was located very far to the rear of the car. This was...
Anyone have any experience with 3 link suspensions where the rear attachement point is behind the rear axle? Currently our car has the rear attachment of the top link approximately 6 inches rear of the axle CL.
In comparing the kinematics of this setup with a shorter top link with rear mount...
I should have said:
I think we are getting close to optimum anti-squat vs. roll steer.
Probably nowhere near the optimum setup overall for the track and driver....
thanks

We're going to be using LVDTs. Thank you for your insights. Load transfer was the main thing I was looking for. And, perhaps, to get some idea of front and rear geometry by analyzing the kinematics with the shock displacements. My simplified model doesen't take into account friction or...
Thanks very much! I've been wondering about the 3 level DOE and trading off the risk of missing an optimum or diminishing impact, vs. complexity in our first try.
Seems we are pretty close to the best combination of static rear steer and roll-steer for our current setup.
Perhaps since you...
Thanks again for all your help. Since yesterday I did more searching on the internet and found your article about counteracting the effects of driveline torque on drag race cars.
Your comments about the differential angles of the lower trailing arms really resonate with me. In fact, that is...
Billy,
I'm trying to find the best way to show you a picture of the excel spreadsheet I've developed. Perhaps my understanding of antisquat is wrong. IC is the intersection of trailing arms, correct? anti squat is the height of a line from tire contact patch to IC as it passes under CG...
Thank you very much for your insights. The IC is at around 11" above ground and the rolling radius is around 13" above ground. IC is about 80" forward of rear axle.
I should have mentioned earlier that the top link also has a spring included, with several rates available. Of course, it is...
Hi, I'm new to this forum and have really enjoyed reading the threads. Hopefully someone can help me with a couple of questions...
I'm involved with a pavement oval track car (2006 Lefthander Chassis) running on a 3/8 mile medium banked oval track with approximately 500bhp. Car weighs 2900...
