Thanks to @BBSBOY for getting everything fitted for me last week.

Definitely a softer pedal feel which I knew to expect however I am not using it daily so haven’t had the opportunity to drive it hard and test them out. Hopefully the good weather keeps up and I can take it a good rub this weekend.

Looks lovely!

Hopefully the brakes stay clean!

Just curious but why does the pedal feel softer?

100% it is the master not quite being up to spec.

A few people bodged on other master cylinders from other BMWs, but I couldn't find any concrete solutions.

You do get used to it though, it sure is worth doing.

Decided to see what all the fuss was about ..

KAVS Motorsport Reduced Super Pulley - went for the 15% Lightweight version and Gates (6PK1368) belt.

Also makes sense to replace the Idler Pulley and tensioner assembly at the same time so ordered the Gates K066PK1390 kit.

Gathering up a few bits and will get it booked in with @Wild Thing in the coming months!

if you are not ragging it all the time i would have tended to go 17%, bear in mind the JCW already runs an 11% pulley. Looks like an oranjje parts list so oli would probably change it out if you change your mind.

Yeh I had a chat with Oli and was tempted with the 17% but thought I’d play it safe with the 15%. Hopefully a noticeable difference.

I also managed to pick up a genuine JCW badge for the bootlid. My original has unfortunately started to show signs of age.

I will replace the Cooper S badge too at the same time.

All fine choice of mods sir.

Mine certainly screamed after the pulley and airbox tweaks.

I left the car down with Brian @Wild Thing last week and had the following work carried out.
  • Gates Tensioner assembly, idler pulley and belt.
  • KAVs Supercharger Reduced Pulley (15%) - Lightweight
  • De-flap of JCW Airbox
  • New Alternator
  • Rear HEL Brake Lines
  • Cabrio Front braces
Pleased with the result of the reduced pulley, not a huge difference, the JCW already has a 11% pulley after all, but it does feel more responsive and with de-flapping the airbox the sound of the supercharger is awesome !

Thankfully no issues reported from the health check. Looking forward to using it a bit more over the spring / summer months. Hard to believe I’ve had it just shy of 2 yesrs

Next up will likely be a wheel refurb and fit the new JCW centre caps along with a few other cosmetic bits.

Great service from Brian as usual. (y)

Tidy looking as always. What sort of bhp is produced with the new pulley?

Thanks Simon, hope you are keeping well.
Its 210bhp with the JCW tuning kit and KAVs claim approx. 15bhp with the 15% pulley - not sure how accurate that is.
