3-link, 4-link, irs - Street use
I'm considering updating my rear to one of the above. From my reading/research, I'm leaning towards the 4-link. However, if I can get the funds saved up, I'd like to look into the Heidts IRS. This is for standard street use, occasional hard driving.. not a track car.
But I had a few concerns/questions about the Heidts IRS, and I'm looking for oppinions here. If you look at the IRS setup, the disc brakes are right next to the center diff. When you apply the brakes, the discs slow the axles, not the hubs of the wheel directly. My concerns is that the braking pressure is applied through 2 u-joints before the pressure is applied to the hub/tires. Does anybody else here think that could be an issue? In a standard setup, the braking force/pressure is applied directly to the hub/tire. I guess I'm concerned about the u-joints seeing a lot of force applied one way for acceleration, and the opposite way for braking... excessive wear? I know that drive shaft u-joints see pressure both ways too, but its not very much pressure during deceleration vs acceleration.
Please keep in mind I'm not trying to knock any products, I think the Heidts IRS looks pretty damn cool. I'm just looking at the braking philosophy.
