Yup, I do.

I bought an RT142 rear disc conversion for my RA65 (I bought these then bought an Ma61 parts car... grr). It consists of RT142 rear disc swingarms, handbrake cables & brake bias valve (Brett, you will need the bias valve, this wasn't on your list). Haven't installed yet but it should be all that is needed - as far as I can tell, the swingarms are identical to MA61 apart from being solid discs rather than vented. Not sure if calipers are different between solid & vented discs, haven't checked.

Mookie's GA65 had had a solid rear disc conversion done when he bought it, and IIRC he was told it was from a Corona, which may be further confirmation for you.

Hope this helps! I would comapre the Ma61 rear end I have to the RT142 one for you, but I'm not near my car right now.

Oh yeah... I installed some rear KYB Super Special externally-adjustables a month ago and they rock

Setting 2 of 4 seems well matched to my King lows, and is a massive improvement over the under-damping Monroe GTs. Can't wait for the matching front pair of KYBs to arrive from Japan....

awesome!!!

thanks alot for the prompt reply

rep for you

also...do the half shafts go straight on? length the same etc?

**Stefan** · 25-02-2006, 09:41 PM

No problem

I don't know if the T-series (RT142) & F-series (Ra65/MA61) half shafts are the same length... I suspect that they aren't (someone else would know for sure). However, I see no reason you can't just use the RA65 ones.

RT142 IRS is F series.

SA63 is the one that is T series

Oh yeah.. the KYB Super Specials I mentioned are JDM ones that aren't made any more (precursor model to AGX as far as I know). Not to be confused with the non-adjustable KYBs a lot of people here run in their A6s, which I have no experience with.

My bad, don't know why I got mixed up there.

I think there is a bit of a difference in thickness but length is the same.

Yes it is correct my car has a corona rear disk setup in it with the solid but i didn't put it in so i don't think i will be much help to you.

The brake pads are from an mx7# i think so that might be something worth looking into.

Also unfortunatly for me my car has the T series diff made out of eggshells and glass but i don't think that should make much of a difference.
