2nd Gen IRS

[exwestracer]

So does that mean you're going with a custom front end? It would be a huge coincidence if those geometries lines up with something that's already out there! I asked Detroit Speed for their front end geometry once to design an IRS, but they said no. Completely understandable, but it would have been cool to design something complimentary.

A little info on how I try to have the students approach a project like this...

We always start a project like this by establishing the lower control arm level in in both planes, then the upper arm mount is located to give the swing arm length to work with whatever tire is going on the project (lower profile= less camber gain). This is all done on the "concrete computer" - drawn out full size on the floor. We will also do the same for the 350Z rear and map out the swing arm length and R/C progression to compare that with the front.

Lastly we look at projected front/rear weight balance and C/G heights (admittedly this is usually an educated guess given engine type, fuel placement, etc.) to come up with an idea of front and rear roll moments and front anti-dive geometry. If we have time (and all the components), we'll weigh the car and do F/R tilt and side tilt weights just to verify our assumptions. Very rarely do we get that far given the time available and the emphasis on learning, not production.

This one is getting a 2X4 rectangular frame, Howe replacement lower control arms, coilovers, and SPC adjustable upper arms. We will be building all the mounts to fit the desired tire size, ride height and geometry.
