MX5 front hubs and uprights, what are the different types?
Are there any differences between the mk1 mx5 hubs and uprights and the mk2.
I have seen that some have an ABS ring but geometry wise are there any differences? also were there any differences in front brake disks and calipers
between these cars.
I understand that the newer ones are 5 stud but wanted to understand the differences between the older 4 stud front upright set ups,
Many thanks in advance

all uprights are interchangeable, '89-'05, only the hubs have the reluctor rings added and the upright may have a mount for the sensor
the calipers for 235 (1.6) and 255mm (1.8) discs are the same, only the carriers change.
one minor point, if you fit 1.6 calipers to 1.8 carriers, you need to swap the carriers n/s to o/s and vice versa to keep bleed nipples at the top,
because the large and small slider pins are reversed. if you need a spare caliper in the future, you either need to swap in pairs, or get one to match
the other side, 1.6 or 1.8.
'99 onwards (mk2), all cars got the 255mm discs, both 1.6 and 1.8
the 277mm 'sport' (and some other mk2.5 limited edition) discs have different calipers and carriers, but the caliper mount pitch on the
uprights are identical between all years and models
235 and 255 rear calipers are the same across all models except the sport, but if you fit 255 discs to 235 uprights, you need to trim some of the
stone shield away, same with fitting 277mm to 255mm uprights.

it might be worth signing up to mx5nutz.com if you have anymore questions. the search is pretty good, but it's an active forum with a good
knowledge base and full of helpful answers if you don't mind dodging a bit of sarcasm here and there
