Well, I can tell you why I am going rear discs, and it is a pretty sad
answer too. It is purely because I got offered a great deal (being a
GREAT deal) on the LSD that I was after... it just happens it came on a
rear axle with disc brakes.
Even fixing the ancillary handbrake etc. rubbish still made it a GREAT
deal, so being an offer I couldn't refuse... I didn't refuse it.
I never really felt it necessary to go discs all round for the track as
I was getting similar braking performance as most of my fellow
competitors. My MetalKing front pads and vented front discs were doing
the job fine to the point of lockup. I reckon I might be able to
squeeze a few metres extra distance before braking but I am not counting
on a massive improvement on laptimes because of it.
But I could be wrong and only track-time will tell.
Now the limited slip diff is another story all together especially on
the circuit full of hairpin corners that I usually compete on - and
maybe the combination of the two will be a benefit. This track is
really a hard-on-the-brakes track and maybe rear discs was what I should
have been going for but it wasn't on my Xmas shopping list.
Given the choice and an extra cost I probably wouldn't have shelled out
for rear discs - but I will report back on the results after my first
competition event on March 14th.
As far as the WOW factor is concerned - yeah, I think it will get some
of that and maybe piss off some of my fellow track mates to boot, so for
that alone it will be worth it :-)
