After doing plenty of research I decided get the Speedy Desert Rat 15x8.0 ET-28 5x139.7's for my 91WT sierra with 2in BL and 2in springs. After ringing around I have now found out that Speedy NO LONGER MAKE THE 15x8 ET-28, which is now supplied by a different manufacturer to Speedy as a ET-24.
Originally I was trying to decide between the Speedy 15x7 ET-15, and the 15x8 ET-28. I had my heart set on the 15x8 ET-28's!!!

I don't really get the whole offset thing (like most of us I think). So my question is:....
Now that I have only the 15x7 ET-15 and the 15x8 ET-24 to choose from, what should I do??? I really wanted the 15x8's but will the ET-24 work on my zook? Has anyone run these 15x8 ET-24's???
Any help will be greatly appreciated!
