gtu to convertable calipers swap
how easy is the swap here? i have a set of convertable front calipers that are gonna be getting out of powder coat in a few days (got it for free for knowing some characters from initial d! XD) and my front brake pads are ready for a change anyways. so can i just unbolt the old ones and bolt these right in or is there some other issue that i will run into later ie: lines wont work, dif thread patern, so on)?? i searched and all i got was turbo II swap threads and other random ****! thanks for any help!

they are completely different. the thread pitch is different on the hard lines. the caliper bolt holes dont line up to the spindles, the pads are different but you said you were changing them anyway. it would be easier to put fd calipers on than the big heavy ancient convertible calipers.
p.s. good job on knowing initial d. that takes skillz as a true drift master to be able to know them.

anyways so i'm going to need to swap out the spindles and hard lines??? (prolly just get braided if i do) is there a conversion kit or an easy way to convert the spindles to fit with the t2 calipers? like i said i have these already and got them for mad cheap so y not.

Assuming two things: 1) by convertible front calipers you mean 4-piston calipers that came on most of the 2nd gen cars, and 2) you have an S5 GTU (like in your picture)... then yes, it is easy.
They will bolt right up to the knuckles (not spindles, as that is only part of the knuckle)
You simply need the hardlines and the flex lines appropriate for the 4-piston calipers as the single piston ones are different.

awesome guys! thanks for all the help! and yes my car is an s5! most of the stuff i noticed between the turbo 2 cars and the na cars seem to be a simple swap but i know a few things dont so i figured it wouldnt hurt to ask before i took this **** apart!
on another note i'm assuming it also uses the same size rotors?

I was about to say, if this is an S4 GTU, then why the hell are you swapping?! S4 GTU has 4 piston calipers anyway.
S5 GTU you'll need new rotors though... S5 GTU got the shitty single piston brakes with 5 lug hubs.

This is interesting. In 1989, the 4-piston setup came with 10.9" diameter front rotors vs. 9.8" on the base cars. See the info in the '89 brochure from the FAQ:

But apparently in '90, all cars had the 10.9" front rotors, so the OP won't need to change them on his '90 GTU:
