spoke to a nice chap at optimum ballance products today and yesterday who was very helpful.
i was looking for a workaround for the pedalbox for the roadster and have found a solution to pedelboxs off the shelf without ballance bars and using a cable clutch as well
single units is the answer buy using a singles pedal boxs to take a single master cyl style and fitting a tandem inline master cyl or modifying it to suit the sierra one hay presto
. (iva man did point out there is no rule not to use a single master cyl for all wheels if i wished)
use a single cable pedal for the clutch and thay even do a throttle single as well
this way you could have what ever pedal spacing you like.
pt no. OBPCL46 for brake or OBP0046 (holes in pedal)
OBP0045 for cable clutch or above for hyd
OBP0048 for throttle
thease are all short type but long types are also avalable (bulkhead distence)
