E9X M3 brakes v E9X 335i Brakes

s2kadrenalin · 02-21-2015, 11:26 PM

Does anyone know if there is a big quality performance difference in our E9X 335i brakes in comparison to the E9X M3 brakes F&R?

A track day a few months ago meant I ran out of brakes @ 210km/h down the back straight after about 15 laps. Some smart handbraking & foot to the floor saved me. Had to let the car cool down for about 30 mins after I nearly ended up in the sandpit @ the end of the straight.

So I'm looking for an upgrade and need your input / thoughts.

The M3 brakes dont bolt up to the 335i, unless you run m3 hubs and shocks etc I have some m3 brakes and looking at them the caliper looks similar to the 335i item, but the rotors are x drilled and maybe slightly larger. What's your budget? Some fresh high quality brake fluid (motul rbf) and some pagid track pads may be all you need? Advan have the nashin bbk which are excellent BFYB.

I'm pretty sure 135i front brakes bolt straight on.

ps: there was/is a set of full e9x m3 brakes on ebay for $600

AFAIK there's no advantage fitting the 135i brakes if he's getting a spongy pedal (smaller rotors on the 135i setup = less heat capacity)

I would recommend going with a set of Nashin's which Advan/BMR sell in AU.

I am personally running a set of these, and they are awesome.

Continuous yeah, but happy laps, just racing your mates down the straights etc.

Sounds a bit dangerous and risky. might be worthwhile investing in something ... potentially lose your life or even worse your car .... no insurance on the track i believe.

These 6 pot Brembos with 380 rotors just came up on ECS which look very nice.

Though I have seen the Nashins at Advan and they also look very nice and have the rear BBK as well.

I do know on the m3 setups with the ECS rotors are quite a bit heavier than the stoptech equivalent bbk rotor (the stoptech setup was cheaper than the brembo/ecs setup also)

Shipping for BBKs are an arm and a leg from US. Probably close to 500 AUD then don't forget about GST and import duty, unless ECS undervalue the goods

Sadily, due to shipping regulations we only declare actual value of packages.

Woah.. What's ECS doing trawling through this section of the forums?! Thanks for the clarification though! What's the shipping on the Brembo front BBK to Australia while you're here?

Grand total (deep breath) $3177.60 (USD) shipped via UPS World Wide Expedited (our current cheapest option for this package to your area).

HERE is a custom cart for anyone else that's wondering what shipping to their area would be.

Unless serious racing, it's really best to do as many cool down laps as hard laps with no more than 3 hard laps at once IMO. Not just brakes getting hot, there's oil, coolant, transmission fluid and tyres too.

You have two options :

1) racing fluid like castrol srf, plus race temp pads, reuse your rotors if they are within tolerance, and set up some sort of front brake cooling ductwork. Advantage is lower cost, disadvantage is the cooling setup requires custom work and you'll probably want to swap between Street and track pads as appropriate.

2) get a stoptech bbk, or another brands readily sold in AUS. Pretty sure stoptech is. Advantage is simplicity/ease of install/effectiveness/engineered solution. Disadvantage is cost.
