I've read the horror stories about GTS tuning, but usually these are just one offs on internet forums...
Anyhoo, i won some suspension polybushes on ebay for £80 described as "Yellow with stainless crush tubes".
After about 2 weeks and a few emails i finally recieved a box with a "gts tuning" sticker on the bottom - so i feared the worst. I opened the package and found black bushes, which wasn't too much of a problem; but then i opened the other bit.
The crush tubes were mild steel tube just cut with a hacksaw.
I emailed them to see what was going on and they said that they could send me yellow ones if i wanted
After a month of waiting and emails i finally recieved the stainless tubes, cut nicely on a machine.
Got what i ordered in the end, just would advise people to stay clear of them as a company, unless you've got no other option.
Dave.
