I know this may sound a bit crazy, but does anyone think that it would be possible to install a set of Infiniti calipers on an 4G Acura TL? Reason being that they look like BBK (called BBK calipers on the posting below), but should be more reasonable with servicing and cost. I was sitting at a stoplight next to an Infiniti coupe and looked over and saw these calipers that looked so much better than stock Acura calipers. Just grind off the Infinti lettering and have put some Acura stickers on!

I know it's probably highly unlikely but thought I'd throw it out there.

And of course after I posted the original question I thought that "of course it would be a problem because of the rotors". unless the rotors were close to stock TL rotors on an Infiniti which I'm pretty sure they aren't.

no it wont work...

it'd be cheaper and easier to get brakes from an MDX to fit on our cars...

you all are forgetting ONE BIG MAIN CON!


Brake calipers from other cars WILL ABSOLUTELY DESTROY BRAKE BIAS.

Engineers dedicate lots of time and thinking to PROPERLY match the caliper piston size(sq feet) with the volume of the Brake Master Cylinder.

adding a bigger caliper(ie; brembos from a different car with a different size WILL FUCK UP your braking)

p.s. BBK stands for Big Brake Kit.
anything more than 2 pistons is considered a BBK.

csmeance

swap master cylinder and ABS unit over too? Plus the rear rotors and calipers!

LOL!

wishful thinking, but we can all dream, right?!

csmeance

If I ever find a totalled MDX, might be worth a shot.

I dunno if he would ruin brake bias. The front and rear caliper are sized to work with one another already from Infinity. It's not like he's putting huge brakes up front and leaving the rears stock, or vice versa.

The proportioning valve may be setup differently, but that can be replaced also.

Brake lines are the same thickness.

You'd have to check the brake cylinder sizing to see if they are the same. Seeing as a infinity G and TL more or less weigh the same, they might be. No guarantees though, but it would be an easy search.

You'd have to run the Infinity rotors with the calipers for sure though. I'm betting those are sized differently from the TL, as rotors always vary from car to car.

I'd say the biggest issue would be finding a method for the Infinity calipers to bolt up to the Acura suspension bits. I think this COULD be done, but it would take more money than just buying the calipers. And at that point I think you'd be better off getting a matching front/rear BBK from an aftermarket source.

^idunno, even a little bit more caliper surface area screws up braking bias.

you're putting something on the car that was designed for another car.
G's are RWD. TL's are not.

what if Infiniti designed the G to have more REAR braking bias?

TacoBello

No, you could be completely right- I don't think this has been done much on cars before. However, even though the G is RWD, most of the braking still happens up front. It would be cool to test the theory out, but like I said, it seems cost prohibitive.

The prop valve should give the calipers the right amount of brake force front and back. However, which do you use? The TL one or the G? I dunno. The TL one might give too much force to the front. The G might not give enough to the front. I dunno...

Might as well just go with a BBK meant for the car...

you could easily fab up a bracket to mount the calipers....
but again, is it a good idea?

i second your thoughts on "might as well go full fledged BBK designed for car"

csmeance

Sometimes BBK's made for the car aren't all that great. For example the Rotora one for the 3G TL.

IMO, I'd rather use OEM parts with spec'ed parts from master-carr to fab up brackets.

A friend put M5 brakes on the 760 with some washers and different bolts. It's a beast.

Just because it has more pistons doesnt necessarily mean it will screw up brake bias or braking. It may have 2 pistons or 4 pistons but typically the pistons are much smaller. The reason for the more pistons is to more evenly spread out the brake force on the pad.

Brake bias is controlled by things other than the calipers so RWD, FWD doesnt matter. Biggest thing to consider is that you keep similar piston surface ratios as stock.

Ive got a set of 6 piston CTS-V calipers im gonna stick on the front of my TL, Most likely get the 4p for the rear as well.

Why?

If the caliper brackets and rotors are properly sized they'd work. The trick would be either finding or machining the brackets.

S2000 guys are running different calipers (like from the V6 Accord coupe) and require a rotor spacer (like 2mm?) to line everything up.

I had NA1 NSX calipers on my '96 Accord - actually direct bolt on ('95-97 V6 Accord brackets, '94-97 Wagon rotors, stock brake lines).

Then you've got guys retro-fitting the Acura RL calipers from far newer cars onto '94-97 Accords - just need some custom brackets and such. One aftermarket company has mass-produced them so they're even easier to install.
