Ride Heights for the silver spindles are:

LF-1 15/16"
RF-2 3/8"

Measure both sides from the top of the lower control arms to the bottom of the frame directly over the top of the lower control arms.

RR ride height I believe should be 4 1/4" from top of lower frame rail to the bottom of the axle. That is what the Rayburn swing arm measurement is...I am not for sure on the rear ride height though as you state this is a 4 bar car.
I have not run the Rayburn 4 bar set-up.
If you had a swing arm (which is actually a 4 bar car, just the top bar is turned around and the bottom bar has the shock and spring on it)...This is a four bar too!
...I could help you more...
I can probably get you close if you want more help than this(PM me with more info). But it will just be to the best of my knowledge on what I would do.

Call Rayburn 877.828.8232 ask for C.J.

4 1/4 should be in the ballpark on the rr & the fronts he listed are right on.

I pit for a friend of mine from time to time and he has a 98' that we run as a 4 link (lr behind, brakes clamped).
500lf 400-350rf
250lr 225rr
j bar 8in off frame rail & center of pinion
54-55 left
55-56 rear
100lbs bite
** He uses a 90/10 shock & pull bar which is alittle different than most, it's has the green spring and the angle is about 15 degrees down.
Approx 1/4in rear steer (trail rr)
This chassis has won a dozen features & 2 track championships in a year & a half...it's not a back marker that's for sure!
Hope that helps!
