I put the adjustable shackles on the car and that helps but it is still not what I would like, it just barely has 2 inches of travel and the weld nuts for the rear seat belts on the underside of the car are still very close to the diff. (I'll be knocking those off) There is still one more adjustment left so I'll see after that. Worst case it will be headed over to my buddies shop.

im at almost 180mm thats with 15 inch wheels and 205/50 tyres

i wouldnt recommend adjusting the pinion angle. with the rpm your driveshaft
endures on a circuit car running your uni joins out of phase will make them fail
almost instantly leaving you with horrible driveline vibrations at the very least.

hey tom , what angle do you have the pinion at? maybe you could point the pinion down a bit and gain some clearance so you can run the body lower and also gain some forward bite in power down out of corners

I'm trying to get a ball park of what ride heights fellow racers are running, I measured mine from just behind the jack point from the bottom of the body join. (the flat 20mm piece that runs the length of the car below the sill) , currently at 130MM / 5.125 inches.

The newly installed H190 has a whooping 1.5 inches of travel and more importantly the Diff snout is all of 1" from bottoming. Note I run the Nismo / Competition leaf springs, which the 1200 competition manual notes are to soft and the rear shackle needs to be modified to adjust the ride height so there is a minimum of 2" of travel.

The two choices are install the adjustable rear shackles or plasma cut a hole in the floor and weld in a new panel that allows for more clearance. Obviously I'll be trying the shackles first and if the handling is fine sticking with that.
