Triumph GT6 race car warming up. After a long winter we are going racing! The brake lines on this GT6 are copper nickel alloy. Please visit my website to purchase a kit for your Triumph www.austinhealeywood.com What we did over the winter: Added a much stiffer rear spring, welded up the differential, Increased the size of the engine crankcase breather substantially, removed the drive shaft and had it balanced to perfection. Also we got of new set of light weight wheels. To purchase Cunifer copper nickel brake line kits for your Triumph Spitfire or GT6 please contact me.
