Chris:
That is correct. I think I started the recent discussion a few months ago. I had
posted the list about problems balancing my LAT 70s (I had three different shops
try to do it with no success, including having them strobe balanced on the car,
and electronically balanced off the car...nothing worked and I got severe
steering wheel bumping over 65-70MPH). Someone from the list (sorry, but I don't
remember who to give credit to) suggested I find a shop with the Hunter 9700
balancer. I did (in Burbank, California for me), and they were able to
completely solve the problem. Even with that, however, it took two trips to the
shop to get it done right. The first time one of the shop "helpers" did the job
and, while better, didn't solve it. The second time, the shop manager, who said
you have to know how to use the machine, did it and got it right on. I've had it
upwards of 100MPH since and the steering wheel is very smooth, even with my
front Spax shocks set pretty tight..
When you find the Hunter 9700, make sure that each wheel is balanced to "0"
tolerance.....the machine gives an exact LED readout as to balance forces and if
you have tricky wheels like LAT70s or LAT9s, any variation from that seems to be
magnified into severe wheel bouncing. If you read the Hunter web site, it even
says, with "lug centric" wheels like we have, for them to use an attachment on
the Hunter machine that simulates how the wheels sit on the car. They didn't
have to use that for my Tiger, but might have to for the LAT9s if they're harder
to balance. Hunter realises that on marginal wheels like ours, even the
slightest variable can cause trouble. Anyway, it was well worth the effort to
me.
