question bout Q45 brakes....

well, i got a full set of Q45 rotors (not sure which year he got them from) and 2 calipers(fronts) for only $25. I was on 240sxtech.com and saw something about drilling out the rotors to be 4 lug acceptable. Is there any pros or cons to drilling the rotor out like that?? i was told i can drill them to match up and put them on and still be able to use my stock s13 calipers. is that true?? i have to get another caliper because one of the ones i have looks like shyt and id rather just get a better looking one. Seemed sweet enough to have the 45 brakes on 4 lug status and then when i evetually switch over-i could still have them for 5 lug status. Well....any help/answers to my questions would be greatly appriciated. thanx dudes

yeah, you can get them drilled. Has to be very very precise otherwise your **** will be off balance.

well if they are the same size as the z32 tt brakes. if you look inside the wheel and it has certain pattern they will clear... ill see if i can find the pictures.

there are two or three different versions.

sweet biggame-that would help alot. The dude i got them from was gone put them on his s14 but was told his 15" Enkei DM5's wouldnt clear them. Something about 16's and up. or maybe his offset was an interference......i dont know. Thanx yall.

well you can always run a slight spacer to make them clear 5-10mm would be enough in most cases.


if you look inside your wheel.. if you have the spokes that are ribbed on the back.. they should clear the calipers... if they are the same size as the Z32 calipers. I don't know much about them because i never did the 5 lug swap or looked into it honestly.

well.....heres where i am at now......i cleaned up the Q45 calipers and got them lookin pretty damn good(cleaned off all the build up-got them real smooth and hit with a coat of Aluminum colored engine enamel). Im not to into the whole drilling out the rotors jus to accomodate my 4luggers, so which is why i am back here-someone at the junkyard told me that Altima rotors are the same size as the Q45 rotors except they are 4 lugged and will fit on my s13 w/o any mods and i can still use the Q45 calipers too. Is this true??

He told me that the Altima rotors were bigger(both width-wise and thickness) than my stock 240 rotors...is that true?? if so....what the hell was nissan thinking when they came up with that one???giving a gay 4-door grocery getter better brakes than a sweet lil sports car such as...a 240sx.

thanx in advance guys

p.s.......was looking over "the ultimate rotor" thread and saw the stats for G20 brakes. The stats say they are bigger and wider(fronts and backs) would those be worth it to swap over?? they arent much bigger than what it says for a stock s13...but nonetheless....bigger is always better.

whats more effective in your guys' mind.....a full G20 brake swap? maybe G20 rotors and Q45 calipers? or the Altima rotors mated up with the Q45 calipers?? i need to get rid of the crappy *** brakes that are on my car now. My buddy told me that, that stinky smell i been smellin(that i thought was a cloggd cat) is actually my brakes. So i did a couple of runs of getting up to 50 and stopping, then 60 then stopping and one last one at 70 then stopping(not a slam on brake and lock up tires stop either haha) and everytime i came to a stop....WHAM the smel was there. Even when i went faster the smell got a tad stronger. Not to mention the steering wheel shaking when i braked too. jus trying to get the better bang for my buck and get better brakes at the same time.
