From experience, the WMS brakes only set you back a little more, with greater future support, bolt on direct upgrade and better braking performance.
I bought the twin pot and it looked insane. Never could get them to bleed properly (read a few others that had similar issues) and ended up like £100 cheaper than WMS brakes.
Also the discs are machined Astra discs, where as WMS uses stock discs. So it means even if WMS go out of fashion, getting discs isn't a chore.
Don't get me wrong, I appreciate the twin pots, but feel I wasted money here for something I should bought in the first place.
yeah, i personally run the twin pot st202 set up...i can't fault it for road use (i dont track my car)
with regards to the bleeding/spongy brake pedal issue, i upgraded my BMC to the slightly larger 7/8 unit from the older ep82 and that cured that issue----the glanza came with 13/16 BMC as stock
getting astra discs is very easy from online....i live in the caribbean and i got them from the uk at reasonable price and they come in many different styles...plus the disc is 25mm thick * 277mm,,,which helps with heat dissipation
i do think the wms set up sounds good as well and seems to get good reviews
i actually investigated the wms when i was making trying to decide which option to go with....but i ended up with the st202 set up
plenty options out there for members depending on thier needs/budgets
