I beleive the only reliable place to get JWT products is directly from JWT.
But for Stillen, lots ppl sell stillen stuff.
First off, anyone who uses KEYSTONE sells stillen, that means Lazer Auto and other shops, and that also means Canadian Tire.
CrappyTire has Keystone thus can get you almost ANY aftermarket part you want, and lots of it is in stock in toronto.
Order from them and its yours in 48 hours. Not always the best prices, but when you need it quick...
Even if its not in the CT catalogue (which is a Keystone catalogue with Canadian tire slapped on the cover), if you have the exact Part number they can still order it.
