Welcome to GT40s, Steve.
Unless you bought a “Turn-Key” or otherwise partially finished car from RCR, they”re typically only assembled in rough state to transport. It is up to the owner/builder of the car to assemble properly and align.
You will need to space the lower control arms as far forward in the pockets as they will go in order to get the wheelbase set properly and to get the positive castor angle. Numerous build logs in the build log forum as well as my own online build log and RCR’s manual will go over this.
Before you do any suspension analysis and or adjustments the car needs to be close if not exactly at it’s wet weight. Engine, transaxle, cooling system, fluids and weight in the drivers seat. The picture looks like an unladen chassis.
hi big foot , what do you mean when you say lca perfectly level ? and i have 205/60/15 front tire , when i drop the suspension the wheel come really close then the rocker something like 1/4 inch the tire rub evrerything .i mesure the center of ball joint to gas tank it give me 14 3/4 how is your ? thksSteve - you need to lift the suspension so that the lower control arm is perfectly level - this will be very close to where the axles will be at ride height. At that point, you should have the increased clearance you are looking for. Also - I don't know what size tires you are running on the front - I think I recall mine being very close and they were 225-60-15.
