Other than not having a huge selection of rims, are there any structural or manufacturing dangers of the 84-85 bolt pattern?

I see some guys switch to the 79-83 bolt pattern or the FC pattern for the brakes.

On my FC I switched to the 5 lug to get the four pot piston, but for no other reason.

My current wheels require an adapter for the F1 style center nuts, yes they are safe. They are full lock with a stop pin (giant cotter pin). And yes they fit.

BUt, like I said in the begining, is the 84 bolt pattern structurally stable, have you had any problems with lug stripping, bearing failure, wheel loss while under stress?

Thanks in advance, Mike 1984 base model 12a (for now)

Something doesn't sound right. All carbed model 1st gens have the 4X110 bolt, the FI GSL SE has the same 114.3X4 as the 4 lug FC. Are the lug bolts subject to failure, not really, can they strip, yes, any lug or stud can strip when improperly torqued. 4 lug wheels have been successfully raced for years with no greater failure rate than 5 lug. Center nuts have an advantage in the pits, nothing more.

Thats the info I needed, thank you. I've just heard too much about swapping but the only reason i can think of swapping bolt patterns for is brakes.

And I LOVE the stock brakes on the fb. Maby try some pad compounds or cross drilled VS slotted. But come on the car is only 1800 pounds brakes are the least of the worries with this car.

But thanks again just trying to avoid some of my "FC" mistakes.

Skip the drilled and slotted rotors, pads will make bigger difference. Upgraded rotors aren't really needed until you push the brakes during a road course or autocross event. I'm currently waiting for the rest of the rear brake parts to complete my TII brake upgrade, which I need for the huge tires on the widebody. If you can currently lock your tires and not suffer from brake fade, your pads and rotors are sufficient.

Unless you have done some radical weight reduction, your FB weighs 2400-2700 lbs.

While the brake upgrade is one reason for swapping to the SE suspension, primary reason it for better wheel selection. Serious brake upgrade is swapping to the FC GSL/TII brakes.
