Hi All,

Looking recommendations for a budget friendly rear disc conversion to my v8 LX Hatch with a standard diff.

Also when going for the RWC would it need engineering.

 

Thanks in advance.

In NSW it’ll need Certification and probably brake testing. It isn’t cheap. Best off doing with all other mods. Unless it’s a track car I’d leave the drums.
You can fit what was optional on any other LH or LX though, so you can fit HQ-WB drums with the Torana axles, you just use actual HK-HG drums with the HQ-WB backing plates & Torana handbrake cables. You’d have to also do the front rotors too, meaning HK to WB stubs, HQ to WB rotors and whichever calipers. Leaves you with HQ front stud pattern and you need to live with UC steering arms or better still repro A9X arms.
What is easy Certification for rear discs though is if you can find an early UC disc rear end, grab the whole differential, booster and master cylinder. You can use the brakes and axles, booster and master cylinder on LH-LX banjo. Will need custom handbrake cable setup, and possibly the rear brake hose and block. Far easier to Certify than aftermarket. The Engineer may want the UC’s calipers too, ask first.

Easiest way is as mentioned a UC disc conversion . Parts are hard or impossible to find though . I can't see it needing engineering because it was offered by the manufacturer . Anything aftermarket will require engineering though . Eg Willwood etc .

By easy to Certify I meant you can do it yourself although I’d be checking as the handbrake is different and needs custom stuff, or at least modified as per A9X.
