to add to Hai's question... what are you worried about camber correction for when you're obviously going for an aggressive setup? The whole point of an aggressive setup is to run wide wheels/low offesets/stretched tires and excessive camber.
-GP-

 

caliper clearance between the wheel has a lot to do with camber. if the wheel face is closer to the caliper, and the caliper is smaller, then i can run less camber. lets say for an example, the non brembo brakes are around 30mm and the brembos are 35-40mm size in width. With the non brembo calipers, i'd save around 5-10mm of space between the wheel face and the brake caliper. That may seem a little, but for camber correction, it is a lot.

yes, but any minimal amount of correction would be needed even if means putting on non brembo calipers.



how much performance will be sacrificed? this car wont be tracked or raced, it's a daily driver. What difference in performance would it be compared to a sedan or an automatic g35?

 

It depends on the additional unsprung weight you'd be adding with the wheels. Are you talking about 19", 20"? Regardless of diameter, much wider wheels will certainly require stronger brake torque to induce lockup, and by going to a smaller setup, you could compromise that, even (especially) on a daily driver. Even daily drivers require the ability to stop on a dime in an emergency situation. Anyway, folks with 5AT 03/04 coupes who have gone w/aggressive wheel/tire combos would have to chime in here.

For the added expense of swapping out the calipers, rotors, uprights, BMC and the booster, which won't come cheap unless you get them from a junkyard, why not just get a custom set of wheels made to fit the Brembos that are almost as aggressive as the setup you are contemplating?

 

9.5 +25 is not aggressive. I'm thinking towards the later. Search for Sin and Robzone's car. They both have pretty aggressive setups w/ BBK ... or used to I believe thier old set ups have been sold now. (Just off the top of my head so someone correct me if I'm wrong). Triple8 knows ... he's been through 1 maybe 2 sets of rims

 

Do you have this info in any other brake related threads? This is gold to me and should be sticky material

 

thanks,

i didn't realize the bmc, booster, and uprights where manditory to swap. I'd figure a lot of 5AT guys were just swapping calipers, rotors, and (new ss)lines. Similar to the 240sx world where we swap 300zx turbo 30mm 2piston calipers/rotors in place of the stock 1 piston stock calipers and still do fine with the stock 240sx bmc and booster. I didnt think that keeping the beefier 6MT booster and bmc wouldn't effect anything.

I've been following robzone and a few others on here, and also know a bunch of z guys that have very aggressive wheel setups and with the my experience with the 240 community and wheels, I know I can make it work.

This thread is just for further research...nothing's set in stone yet.

 

I personally run single digit offsets with brembo's you just need to do your homework

 

This is only true if you use the same sized lip on both wheels with different faces. If you use a wheel with a 10-15mm smaller lip then you end up with the same offset and camber clearance.

 

what do you think i'm doing with this thread??

also, the owner might want to run negative offsets...
not sure yet.

 

I have a set of non-brembo 03 brakes if he wants to trade.

 

Please.. don't make such a idiotic comment like that.. You obviously are brainless about cars. People without brembos have much better luck to go big lip without camber the crap out of their wheels like me...

 

I suppose you could get away with keeping the bmc and booster, but I'm guessing the feel will be very different. You will probably need more pedal effort to stop the car since the BMC and booster are sized for more caliper pistons and bigger rotors, but this is just a guess. Can't say for sure as I've not heard of anyone doing this reverse swap.

 

If anything, it would feel better. More power to less piston area.

 

Right - I was thinking backwards. Smaller BMC piston area would result in greater line pressure. Wildcard is the double-diaphragm booster - not sure what the effect from that would be. It could result in incredibly grabby brakes with little modulation ability. Hard to say for sure...
