I run my '75 B in autoX, I have installed quite a few modifications, and as a
result I run in DSP. If you are looking at trying for a national title, either
build an all out competition car or look for a more competetive modern car.
For my money, the B is a really fun car to drive and race, and in the smaller
clubs I race with it can even run up front. I have the wins to prove it.
I have the Addco 1" front sway bar on it.
Also, you will want the negative camber A-arms, firmer shocks, and the single
biggest improvement you can make for auotx is tires. I also have the braded
steel brake and clutch lines, they are nice but not necessary, you will want
to focus on brake pads and shoes. Install better pads of a harder compound.
You don't want them too hard because then they aren't likely to get hot enough
to work. High performance street compounds should do nicely. Because my car is
a rubber bumper car, I lowered it and added the huge front bar, along with
Addco's bar I installed their adjustable end links and poly bushings, this
allows some tunability of the sway bar, and keeps it mounted very firmly to
help provide quick response. Also, upgread every bushing in the front end that
you can. The car will ride some what harder, but it will pay off big on the
track. While you are buying sticky tires, buy wheels too, lighter alloy wheels
mean less unsprung weight on the suspension, which helps in the responsiveness
area. Consider slightly wider wheels but no wider that 6 inches with the
proper backspacing and offset. I also have some bolt on engine mods, but
strongly recommend some drivability mods for competition, first off and
probably the most beneficail and most over looked is a good driver's seat and
harness.
You want the driver to stay still right behind the steering wheel throughout
your run so a seat that is firm and very supportive combined with a good
harness system that is fastened as tighly as you can stand it is practically a
requirement. If you are flying all over the place as the car is going form
turn to turn, you will not be able to maintain total car control because
you'll be struggling to stay in the car. Also,a steering wheel with a smaller
diameter will result provide the effect of a faster ratio steering rack.
Hope this is helpful, I know it's a lot but you don't need to do everything,
it all depends on what you want. Good luck, and when racing always remember
these 2 rules.
1. Wide open 'til you see God, then brake.
2. Autocrossers go in deeper and come out harder.
Have fun !!
