Be nice to us peasants and test the brake changeover with stock tires/wheels before throwing on the new hooves.

Re: WK2 SRT Brembo brake kit on an Overland

Size matters. That's it. Bigger disc, bigger calipers, better brakes.

I can start making a 10,000 word post with physics, dynamics, test, etc but bbk will of course perform better than oem in every situation, even in a 60-0 oems will be working let say at its 80% when bbk will be at 30-40% of their power.

And the looks they offer are worth every penny.

BTW they are no aftermarket bbk for the wk2, but who knows maybe soon.

Re: WK2 SRT Brembo brake kit on an Overland

I had a bracket made for a front brake upgrade on my WK1.

Wilwoods are thinner and lighter than the Brembos(4pot) so you might not have to do anything to the wheels.

Re: WK2 SRT Brembo brake kit on an Overland

Wrong size may not matter with brakes. Best OEM brakes out there Porsche and then BMW. BMW until recently has been using one piston and at the most two piston calipers up front. Even on their M's. For track day use at tracks tough on brakes there are no issues with the proper fluid and cooling.

If you want shorter braking distances the most important thing is tires. Low rolling resistance =longer braking distances and AT or MT =longer braking distances. Next is pads the more bite the pad has the shorter the brake distances will be. Remember pads and rotors are consumables. Next you need to worry about cooling. Ducting and removing the backing plates help. Brake fluid you want a quality fluid with a high wet boiling point and you want to change it very 12mos. Do not buy the ultra expensive racing brake fluids with the high boiling points. Why you ask? They attract water vapor very quickly. Stainless brake lines from Earls provide a nice firm pedal and offer some offroad protection but I am not sure they reduce braking distances.

Now if you think I am full of it read Carroll Smith's books like to "Tune To Win", "Engineer, to Win", "Screw to Win" etc and spend a little time at a SCCA race and check out the cars running in the IT classes and Showroom
Stock. I have been a SCCA crew chief or a GT3 and SR car for a number years and was on the pit crew for winning 934s and 935s in IMSA.

Wilwood 6 piston calipers are about $350 each and the 4 pistons are $320 each. Figure $200 each for four rotors maybe more , 4 brake line from Earl's maybe $200 +or-, and you need adapters for the calipers. You may need a new master cylinder and I am not sure if the electronic nannies need to reprogrammed. Remember in deep snow and gravel you will stop shorter w/o ABS.

A GC is not a track car. Price the Euro ventilated rotors for the rear, go with better pads and find a good summer performance tire if you want shorter stopping distances. You just saved enough money to make your SO happy by buying her some La Perla and Jimmy Choos. So do you want to stop quicker or?

Your call.

Last I checked BMW M5 front calipers are 6 piston and M3s are 4 piston

I had a 2010 M3 Coupe prior to the GC and it had single piston calipers front and rear. But they did work well. They also still use a strut front suspension and again, they handle quite well.

I stand by my statement. My research shows both 2013 models have them.

Model year 2013 M3 info isn't available yet. So the 2008-2012 M3's have single piston calipers front and rear.

"Based on the spy shots, the car appearance is low, wide and impressive with the massive fenders, sporty front bumper, large Brake Disc and 4 Exhaust pipes. Besides, we also find that there are 4 piston fixed caliper brakes at the front and 2 piston fixed piston calipers at the rear axle."

"We also spot 4 piston fixed caliper brakes at the front and 2 piston fixed piston calipers at the rear axle, mated to the M trademark slotted drilled brake discs. BMW Mís newly developed active rear differential will likely make it to the new M3."4

I like your need to call people names. I know it isn't for sale yet. I am stating that they have obviously found something that brakes better.

Please learn to use an apostrophe when you post.

Try a bad set of tires on a Ferrari scuderia, or a brand new sets of tires on a civic. Brakes are the ones that actually stop the car, not the tires. Its like saying that a good set of spark gives more hp's than a turbo.

BMW using 1-2 piston at front? maybe in the base models, not on the performance ones. Lets se the new M5 caliper, how many pistons are there?
