Can someone with an SR20DET swap give me a measurement on the 4 corners of the frame under the floor of the car? basically the flat part after and before the upturns on the ends.

Thanks!

Can you show a picture of where you need the measurements? I am confused about the measure points. You can pm if you want.

I think he means the bottom of the frame rail to the ground on the straight section between the wheels, approx under the antenna and before the rear axle kick-up so he can set ride height.
IIRC, the later cars have a reinforcement/lump welded on at the front that will hang down about 3/4 inch, so keep that in mind.

Exactly. I need those points so I can set the ride height in my CAD generalization of the car so i can position the new front and rear subframes (from a miata) in place so i can figure out how adapter them in.

the flat area under the middle of the car is perfect. maybe at the corners of the X brace?

Ok. I have super comp springs from Dean, stock 67.5 rear leaf springs with a RX7 rearend. I'll take some
measurements tomorrow.

Measured Wicked Lady (my red swap car). Front 4 3/4", rear 5 3/4". Last flat spots before frame goes up.
