Wow. A 4" spring of any reasonable rate will bind in 2.5" or so. Will that leave enough bump travel for you all?

 

People definitely use 4" springs When your rates are in the four digit range, there isn't all that much compression.

 

Maybe I'm just not low enough, but 6" springs give me enough clearance. Though with my camber plates I don't need a short spring (I do run a 6", but keep the assist set up). I just adjust the camber at the hub to give ~5mm clearance from the tire to spring and it seems to be enough not to rub the 285 BFGs that squirm a ton on a 10" wheel.

How low are you guys running?

 

4" springs are too short for the front, but work fine in the rear.

 

YEah I looked at Hyperco's website (rather than looking at my car) and I think Marshall is right I use a 6" spring with a tender up front.

Nollij,
JDavenport wants to use a 275 because of his class rules.

 

Yeah, that's what I was talking about with my post... Didn't realize we were talking front springs
