Depends on a couple of things:
- taste: turn in vs. traction
- engine power: guess you have 300+ HP > traction needed
- LSD or not: guess not > you need traction
. camber, tyres and so on
Think you better go for a 'mild' front ARB, so solid 24 or 25 mm.
I'd have a look at the Whiteline.
Alternative: lightweight hollow tube type 27 mm, but I don't
trust the hollow bars since I saw pics of two cracked ones.
