Red top 180

R34 GTT brake/Hub upgrade on a 180sx

Recommended Posts

I was doing some researching trying to find some 5 stud hubs for my 180, when i came across a car wrecker selling a full r34 gtt brake/hub setup for cheaper than most bare hubs, just wondering if it would be much of an upgrade over the factory sr20det s13 setup? And would it be straight bolt on?

Front hubs won't fit, all the rest will. Front knuckles will need caliper mount holes drilled to 14mm iirc. Handbrake cables will need an adapter

Hmm so if I source some compatible front hubs the rest will work with only small modifications here and there?

You can get full 5 stud conversion kit off eBay for 5-600 and it fits.

Im interested to know if the calipers would bolt on to a 180 with 5 stud already done. i currently have s15 calipers on 280mm rotors but need more brakes for track

Caliper mount holes need to be drilled out to 14mm I think.

 

Caliper holes line up 100%

Drill out to 14mm and use R34 GT-t bolts and bob's your uncle.

So from my reading bm50 non abs master cyl would be best with an r34 gtt caliper upgrade.

But atop of this if i have a 5 stud rear would they go on or is there more tricks to be had?

Or would r34gtt fronts and s14 rears be ok?

Track use only no road use at all

It's "OK" but not good, match your rears to your front - especially for track use.

Agree after more reading.

Looking at r34gtt front and twin pot gtst rears now i rekon.

Just attempting to sort out 3 port non abs bm50 for it.

Buy abs bm50. You can drill and tap the 3rd port into it.

I did it to a bm57 with no problems.

Use the master suited for the brakes your using so if you're using r34 fronts and R33 rear use r34 BMC.

Ordered the r34gtt front and gtst rear with hanbrake drum and all components.

See how we go.

Hoping its worth the effort over the s15 front and s14 rears i have on there now .

Also get decent rotors and brake pads. If you can spend a bit more and get the project mu rc09 never had issues with big high speed stops and the initial bite is really good.

How do you think the Type - D pads would fare for hillclimb stuff? No good as not in operating temps?

I've installed it into my car and also Phil (the other member of trak-life) will be running them all round on his S15

 

So far I've driven around town in them, they seem like normal pads. No squeal, etc.. and they stop fine.. the real test will be the track!

 

I think for Hillclimb stuff they "should" be ok, however Intima SR might be a better fit!

Its a track only / trailer car if that helps. Will prob do more track than anything else.

I'll do a review of the Type-D pads after the 30th of May :)

 

So far street driving on the Type-D doesn't do justice

don't use the holfords bmc. mine never worked/felt right. i have used it with r32 gtr calipers and r33 gtr brembo calipers.

just get a bm50 abs and take it to a brake shop and have them tap the 3rd port. that way all the factory lines are used and is neater.
