Roll cage

I am looking to buy a roll cage for my 197 track/race car build. Weld in preferred, but not a deal breaker.

I have seen MG racing one one ebay- 172340858533 (they do a full cage), and also one by Alachi57 - 142126484850, anyone have any experience of these. Both the sellers suggest they are FIA approved.

I would like fitting if poss, but again not the be all and end all.

The Safety Devices at 1K seem ok, but its not cheap when likely cost to fit will be 400-500.

Any suggestions guys.

If anyone has one for sale, please shout up - matt 07872330628
 
I have the Safety Devices 6 point bolt in cage, it was easy to fit using basic tools.

I would recommend buying from Mark Fish Motorsport and that can also fit it.
 
I'd go with SD. It's a proper cage designed to do a job. A poor cage just thrown in on existing fixing points it probably more dangerous than no cage at all.
