Boss 338 Wheel Group Purchase

Not starting one but sharing a link to one already in progress...

The Chevytruck forum has started it's group buy for these wheels and you won't believe the price they've got.

I ordered a set of four 20X8.5in rims for my truck for $605 (+shipping+tax) in gray. These are the same 5X5 bolt pattern we need for B bodies.

They are offering sets of 4 rims in 18 and 20" in different width combos

Group buy thread is:

info thread is:
http://67-72chevytrucks.com/vboard/s...352320&page=28

Second group runs till next Thursday (4/1/10-no joke) at 3pm
If you've interested in these wheels these links are worth a serious look!
Contact them to join the buy

B-body offset thread is here:
https://www.impalassforum.com/vBullet...d.php?t=228471

BOSS wheels tech specs are here:
http://www.bossmotorsports.com/wheel...ecs.cfm?id=408

I was going to get another set of 18X9.5 for my Impala but the offset is a bit shallow per the thread above. Not sure what real-world difference it would make..

I ran a comparison for a stock Impala SS wheel and an 18X9.5 BOSS wheel at: http://www.e90post.com/forums/showthread.php?t=130963

the boss wheel is 10.37" overall width and -4mm offset (5.031" backspacing)
Calculator said:
"1mm LESS clearance on the strut side, and the outside edge of the wheel will EXTEND an extra 21mm"

So about 3/4" closer to the fender lip than SS wheel

18X8" wheel (+2mm offset, 8.876 width, 4.517 BS) compares as:
"12mm MORE clearance on the strut side, and the outside edge of the wheel will RETRACT 4mm"

Hmmm....

I'm thinking the 20's are sounding good to me. Anyone running something like a 2653520?

20x10 test fit, My measurements came out to me only being able to run a 285 without rubbing anywhere on the inner fender.

09 G8 GT, lets just say modded
95 b4u- basically sold sadly
2009 jeep cherokee- sold
2014 grand cherokee
