To FC-V8,
In response to your question "How much tyre clearance are you getting between the steering arm using LX rack on HR front, HQ brakes?"
I took some quick pics of my tyre clearance to modified steering arms. (LX rack on HR front).
modified HR drum stubs, Hadfield HQ brake adaptors, HQ rotors. "outa the box stuff" for the kits supplied.
First shot is standard HQ rim with 195 section tyre (I can squeeze my finger between the steering arm and tyre.. so approx half an inch clearance.
second shot is the GTS rim with 225 section tyre ( about quarter inch clearance), I doubt I will use tyres this wide on the front.
third shot, same as second minus my finger.
I hope this help answer your question.
Sorry for posting it here, FC-V8 has no email, hope its of benefit to others too.
Cheers
Ed
