These are my door cards, they're plastic that has been carbon wrapped.. The previous owner made them, might be worth having a look through his progress blog http://www.ukstarletowners.com/topic/58397-dans-99v/
I've just purchased the overhaul package, spoke to Mike at TD and asked the same question, he said the twin core will be good enough, unless you're planning to run a forged motor and big power really. Then the triple would be worth it
A few small updates, the cage is now out as it was a pretty poor fitment, and as this is my daily it was beginning to do my head in. Also bought a Cusco Carbon rear strut brace from RHDJapan to keep up the carbon theme on the inside. Slowly beginning to plaster it with stickers...
Bought a Cusco carbon rear strut brace for £112 or something and paid about £40 delivery by FedEx. After it arrived there was a £17 charge for import duty and taxes... Don't know if that helps haha
Never had rainsports, but heard such good things about them... I run Goodyear Eagle F1 GSD3's, can't really fault them, very grippy, especially in the wet. But they're only 45's and don't come in 50, doesn't bother me though I prefer the 45's.
