brakes question

realscot · 22 Apr 2007 at 21:51

I was wonderin if the Honda Civic 5 Door (one with the rover shaped body) shares the same discs as a MG ZS 180. I had a look with the wheel on (best i could do at the side of the road) and I noticed that the suspension looks identical, and since they basically use the same parts on the MG's as the rovers, and hence the 5 door civic.
The civic has 282mm discs on front and 262mm on rear, i've yet to find out the size of the MG's as google seems to give me everything but what I want to know. Thought there might be someone out there that would know these sort of things.
I do know that the Civic and MG can use eachothers wheels so the stud spacing must be the same.
Also if there's any honda experts out there, do u know if all the B18 series engines use the same exhaust manifold/header? i.e will one off a B18C1 fit the B18C4? I'm just talking about the engine side, not caring about the cat connection as that's easily adjusted.
Thanks.

ooh it must be civic night!

Done some searching for you (helps me as well!), not sure about the ZS brakes but theres a bit of info there.

I believe any B series manifold should fit, however saying that, I have a Tanabe one on mine, for the Integra, and whereas it fitted, required a bit of fettling by the local garage to get the hanger bracket and cat replacement to fit. Shouldnt be too difficult to sort tho. Any B series will fit, B16 mani's will sit a bit closer to the sump though due to less clearance.

thanks for the reply Gaijin. it's looking like the discs will fit both cars, but the pads are different.
As for the exhaust I will find out on friday if it fits as it's going in to a stainless exhaust fitter to get my DC Sports 4-2-1 mani for a B18C1 (usa spec) onto my B18C4 (euro) and they will custom fit a decat pipe in for me as well. It's gonna be made so that I can put my CAT back in for the MOT should I need to.
Been told the modding of the Manifold (to fit cat side) and making the cat replacement pipe, will cost me £100 all in.
I think that's not too bad a price as it'll probably take a couple of hours to do.

Picking up on a point on another thread I saw about stability after lowering your car... About 2 weeks ago I fitted Koni Red's all round with progressive lowering springs. It's had about 500 miles to settle down and is sitting just the right height for me, and isn't bouning all over the place like some lowered cars.
Last night it had rained pretty heavy and on the way home the car felt really nervous and twitchy. I'm reckoning that the wheel allignment will be ready for doing now, hopefully that'll see things right again. Funny how it feels rock solid in the dry!
Tyres are toyo T1-R (205/50/15 on stock alloys) so plenty of grip there. i gotta say they don't last very long though!!

According to this the ZS180 has 282/260mm discs.

According to the catalogue I use at work, they are different discs.

Get a manifold with the JDM 2.5" collector, gets the engine breathing much better.

4-2-1 on the 96 spec JDM Teg and the Ek9, with a cast manifold and tubular downpipe. The JDM 98 spec is the nice 4-1 unit but really you need valvetrain mods to make the most of that one and will cost more. Anything B18 is okay, B16 stuff will be too short and foul the sump. The Ek9 B16B however uses a B18 block (P72) so its okay.

The PCD on the MG brakes wont match the MB6 Civic, 4x100 vs 4x114.3 repectively.

The MG's have a different caliper whereas the Civic is the same as Tegs, prelude, Legend, NSX, Rover 600's and have a nice range of aftermarket pads. No merit swapping from what you have at the moment just a nice set of pads will; be more than capable braking.
