Parts + Techniques
T/E/L + Galant VR4 (?) rotors 276mm vented 4 bolt
1989-92 CSM/Lancer hubs regardless of turbo or non turbo need to be machined down at the hub center ring
Disassemble wheel bearings with press or like technique
T/E/L (?), Diamante, or VR4 twin pot calipers with 6mm spacers
Reuse all factory bolts in this process, or need for upgrades (see below)?
i also used new longer bolts to bolt the caliper on, 35mm vs the stock 28mm.
Engineering point of view
Longer wheel studs have enough thread depth in the stock lug nuts now?
i part number checked the T/E/L GVR4 wheel studs with the C/S/M's and they are the same, i assumed because the T/E/L has the rotor on the outside stock that the studs maybe longer to compensate. that is not the case.
Will factory 14" wheels clear this new set of calipers and rotors, or would 15" be the new minimum for T/E/L with twin pots setups?
Does this new rotor position and subsequent matching position of the calipers and brackets mean that the whole aligned assembly is being moved 6mm outboard and the caliper is not physically moved 6mm outboard without the bracket coming forward too? <- Just for reference because I'm pretty sure that 6mm would leave only one brake pad to work with!
the whole caliper is spaced out the same amount as the rotor, 6mm, so it align's as per factory, the spacers go behind the caliper bracket inbetween the hub caliper mounts.
Is it worth it, to bolt (using the old hub to disc bolts) the new rotors to the hubs from the outside?
Would you recommend new hardware when doing this?
i dont believe so, that would require drilling the rotor, and then your in the same position as before, stuck with captive rotors, but on the other side of the hub, you will also still run into wheel fitment problems as per the stock setup.
Because of the aforementioned question, will you have to drill 4 new holes in the rotor to accomodate bolting the rotors to the hub in this new fashion (from the outside of the hub surface)?
see my above reply
This will help clear up any issues rather nicely.
Don't be afraid to correct me on anything here, because when it comes to brakes, you cannot take a chance and I do not pretend to know it all. You are just one pedal stomp away from delivering your car into the back of another if things aren't designed properly to work fully in unison. Don't get me wrong, I'm absolutely not criticising t04garret, this is the opposite, as I am looking out for people that do not work around brakes all the time, and, that want 100% background on what they are indeed going to be bolting onto their car.
