Fitted roll bar with mounts...

Depends on where the fixings are for the shoulder straps. You may find the fixings too close for most standard belts and the adjusters wont take out all the slack. Ideally the adjusters should sit at about nipple height. If you are just doing track days one that joins the shoulder straps into one fixing is OK but they are no longer acceptable for any regulated motor sport use. 3 inch belts are easier to handle but 4 inch ones are more comfortable if you “lean” on them. Get one with a proper “aircraft style” buckle and avoid ones that use normal car belt fixings. More expensive ones have nicer (easier to use) adjusters, this may seem unimportant once they are adjusted but you may want to put the belt on and then take up the slack each time which makes the extra cost worthwhile.

If a standard belt wont fit Willans will make one with custom lengths they have made several sets of belts for me, found them very helpful.

Wouldn't advise a harness for road use, stops you seeing at junctions.

Steve, thanks for that info.
I did intend leaving the original belts in for road use.
Seems its not that easy to fit even though the roll bar has the rear anchor point around nipple height it is only a single anchor point which would take both rear straps.
Thanks again.
