Anyway, I'm uncertain what you're asking re the heights? Sure the SRT wheels can take a taller tyre, surely you'll be deciding on what tyre height to go with once you've sorted your clearences?
Even with the unusual offset of the Aussie SRT wheels, the WK has the same tyre clearence issue with "The Bolt" clearance as all the others.
Thanks Marlin for the reply. Have you seen written specs for the WH SRT wheels and is the 6" of Backspacing and 25 mm offset correct?
The reason I am asking about how tall I can go is the the less the offset, the more you move away from that bolt. The problem I am facing is working out how much clearance I need to leave above the upper wishbone and the underside of the gaurd. I what the Willys as low as possible without hitting the underside of the gaurd at full compression. Just taking the spring out and fully compressing the strut wont tell me how much extra to leave for the compression of the bumpstop under a hard hit. Would be very painful to see a big dent rising up out of the gaurd of a nicely new painted hotrod. So fitting taller tyres would allow me to build in more clearance in that the wheel wells will be nicely filled without lowering the Willys as much for the same look.

Re: Stock SRT with 20x9 all 4?

To answer your direct question mate, no, I cannot confirm the WH backspacing or offest.
Can the seller measure for you, or indeed is it stamped behind the wheel somewhere? Usually on the back side of a spoke.

Re: Stock SRT with 20x9 all 4?

Asked him to put a straight edge across the back of the rim and measure down to the wheel mounting surface. He came back with 6" exactly so just hope he did it right.
Using this chart here. https://www.rsracing.com/tech-wheel.html it give +25 offset for a 9" rim. Just thought it was odd as expected them to be the same offset as the front SRT's in the US with 34.75.
What tyre size does the SRT Aussie spec run at on these wheels?

Re: Stock SRT with 20x9 all 4?

I think it's 255/45/20.

And i too would be Very suprised if these wheels didn't match the US fronts.
In fact, I bet they are the same, and a mistake has been made measuring the offset...... my gut feel is the measurement was taken from the edge of the wheel rim instead of the inner edge of the bead, because the bead measures about 5m.

Re: Stock SRT with 20x9 all 4?

I asked if he would tell me all the marking it had on the back of the rim. This is what he came back with.
RS 151
2080
P+40
E0701
S1

Any one decipher these for me? I only guess but would have thought the P+40 would be the offset, but would not make sense with the 6" back spacing he measure for me?

Re: Stock SRT with 20x9 all 4?

hmm, never seen offset marked as p+40 before.. usually just +32 or something to that effect.

if they are SRT8 wheels then they must be from the old 2006-07 models and limited to RHD vehicles because around here its the same as the states the 08's came with 20x9 and 20x10 wheels and were polished (they also had "Alcoa forged" stamped into them)
I know Australia is a big country and this may not be possible, but if hes not too far off, then just why not just give him a visit and test fit the rims.. thats the only way you can be 100% sure.

Re: Stock SRT with 20x9 all 4?

you need to determine if the brakes on the WH SRT are different than the US WK model. If they are the same, the +25mm off-set will not work. I just bought aftermarket wheels for my Jeep that were on a SRT, and the off-sets were +32mm front and +45 rear, but that is on a 10" wheel. So IMO the off-sets would need to be +32mm at the minimum, unless the brembos are different in which case I like the wheels and you should get them if the $$$ is right. Good luck

I'm afraid he is one one side of the country at the far west and I am on the east 3500 km away.

Same Brembo brakes here. +25 moves the wheel even futher outwards to give even more room than the stock in the US fronts of 34.75 mm.

The Yankee-Doodles got the staggered fitment, and polished. Personally, I'd hunt down a US set, unless those Oz ones are dirt cheap?
you forgot Canuckians too Marlin
