0 Replies and 1335 Views Converting to coil-over shock  1335  0 Started by  sgt_g Ok car in question is a 2010 ford fusion awd sport. Factory configuration has a shock mounted to the hub and then at the normal angle to the car chassis. Then the spring is mounted on a control arm inboard of the hub about 3 inches. I have a set of Koni 30 series shocks to go in place of the factory shocks that I plan to mount inverted and I am thinking of getting the kit to convert it to a coil-over shock. But I don't know enough about suspension dynamics to know what that would do to the h...

The rear half shaft angle I've found different info from setting them parallel to the ground at ride height to setting them angled down towards the ground 1/2' from ujoint to ujoint. So what's ideal for autox/road racing Once I have this I can deal with the toe adjusters and get those level because there about 1degree pointing up and that's with my half shafts pointing down 1/2' towards the ground ...

9 Replies and 5872 Views Coil Over Conversion – How Do These Rates Sound?  5872  9 Started by  kpgubert First, the car is a '94 Mustang GT convertible, 3400 lb. Have been running 275/40-17 A6s, but I would like to graduate to 315/35s sometime. I realize it's never really going to be a nationally competitive car, but I still enjoy running regional/divisional events and making it faster (driver mod required too). It's still licensed, but I rarely drive it on the street. Right now I have the springs in their stock (inboard) location. The fronts are 950-1050 lb/in H&Rs and the rears are 415-515 ...

3 Replies and 6142 Views Ideal wheel rate to corner weight ratio  6142  3 Started by  dgoetz I am in the process of ordering custom shocks and springs for my Emod. I have already calculated my frt and rear motion ratio, wheel rates, corner and unsprung weights. From what i have read the ideal autocross wheel rate to corner weight ratio is some where between .8 and 1.2. In other words if i have a front average corner weight of 450lbs the ideal wheel rate to corner weight ratio would put the wheel rate between 360 to 540. The rear average corner weight is 490 or ideal ratio between 392...

6 Replies and 3548 Views Can I still run my 7 clone in D or E Mod?  3548  6 Started by  cboettch Hello all. l'm looking for some guidance (forgive me if this is long winded) I completed a scratch build, street legal, 7 clone last summer and competed (I use that term loosely, as it was my 1st year) in DMod with my local club. (1.6l NA, 1300lbs). I say competed as I am a class of one in Mod. As winters are long (Manitoba), and I enjoy working on the car as much as drivng it, I built a turbo system for it. I didn't do this with any class in mind. It was just a cool learning experiance ( like...

His e mail is I vote yes as I am in CM and it gives us a much better deal. Before the ProSolo season officially starts we have had an interesting conversation with a few folks and are possibly thinking of changing the way R1 and R2 is formed in the Tire Rack SCCA ProSolo series. The current model is R1 is all Modified classes and R2 is all Prepared classes. Each running on index to determine class rankings. However, the idea brough...

8 Replies and 5234 Views Prepared classes shuffle coming  5234  8 Started by  hanhenze Looks like the SEB has confirmed the rumors I heard a Nationals. GP is out and those cars have been split into EP and DP. I'm about to test my DP build and some weight changes are in the mix too. They're giving the 2 valve per cylinder cars a break.

I am looking for anyone to point me in the right direction as far as reading material ( an actually book would be nice ), however I am open to anyone helping me out on this thread as well. The Datsun 510 utilizes a semi rear trailing arm suspension, where it is prone to camber/toe changes over bump travel. There are some interes...
