Hi i'm bodging a seat ibiza roll cage into a mk2 golf, but it doesn't really fit well the rear legs are narrower and dont meet the rear wheelarches. So i imagined hacking the rear part off but leaving some stumps, which i can sleave new tube over. I have some thick wall ali tube at work and a pipe bender. Do we think ali rear legs would be a bad idea? car will be mostly road use and occasionally track day
use steel if you want to do track days etc... plus the cage will presumably be steel anyway if it's come out of an Ibiza Cup car (off Ebay by any chance?) & I don't think welding ali to steel works too well does it (I've never tried it tbh)?
was thinking of sleeving the ali over the steel stump and bolting/clamping it didn't a lot of proper motorsprt cages used to be ali up until 10 years ago?
Yes, but the very reason they got rid of them was that they are brittle in nature and break. If you're doing a cage, do it with 100% CDS steel, or not at all.
Doesn`t work at all. Structurally aluminium can be as strong as steel in some cases but to construct a full cage from ally would be expensive to buy material and even more so to weld. Steel is the sensible option when all things are taken into consideration.
