Refurbing Speedline alloys- 1990 CQ20v

ken0204 · 05-08-16, 04:34 PM

Hi All,

How do people who have refurbed their original one piece Speedlines get them acid dipped without melting/dissolving the plastic rivets/ bolts ?

Or do you buy new ones and press them in ,as they are only for decoration?

Where can you get these new rivets?

Thanks

Drill them all out. Only 30 per wheel. 5mm drill bit will do it

I used 6mm flanged socket cap screws to replace them

One of few subjects I can advise on as mine were done just last week. You can't save the article studs, the acid will melt them and if that didn't then the oven would anyway. I pulled all mine out with pliers, they are only on splines

I could only find one place in the UK that stocked plastic studs the right size and they were over 80 quid for 80 of them! The hole size is M7 and with M7 also being a non standard size M7 bolts are very expensive too. You can either get 6mm stainless cap heads and bond them in or for a tighter fit I bought 1/4 UNC stainless socket caps which equate to 6.5mm and cost me 30quid for 120 of them

Thanks for all your great comments and information. What bonding agent did you find the best to stick in the stainless socketscrews or did you cut new threads by inserting the socket screws?

Cheers ,

Ken

I used this on mine

Seemed to have worked really well. Was a bit of a messy, long job. Took me probably 1 hour 30 mins per wheel.

On mine, most of the screws formed threads when fitted. The odd ones that didn't were loose and got a tiny bit of superglue to hold them in place

This place is a mine of information. Thanks for sharing. I was thinking for doing my wheels soon so this helps a lot.

What's the correct tyre size for Speedlines?

I've got a set coming for my 90 but they are sans tyres.
