The Mopar parts catalog only said that the kit required 17" or larger wheels, so I assumed the stocks would fit. A spokesperson at Mopar said they knew the stock wheels might not fit and had "assumed" aftermarket wheels/bigger tires. Supposedly they will modify the catalog entry.

Yet reading other posts it appears people have installed the kit with stock wheels? Was it just something about my 2007 wheels?

Anyway it was worth the upgrade for me. I noticed a big improvement in stopping power.

That Mopar explanation doesn't make any sense. Because if someone "assumed" aftermarket wheels, then they would also assume bigger tires, which means longer brake lines, which the kit does not come with as just discussed. If the calipers rub, it's because someone didn't test it on all the stock wheels or the rubbing was overlooked. That Mopar explanation just sounds like marketing department B.S. in an effort to minimize a mistake.

I'm going with the 3rd route. The reservoir does not to be very large, you just need somewhere to mount it. Motorcycle brake/clutch reservoirs are large enough and are cheap online. Some cars/trucks come with separate reservoirs as well, so they can be found fairly cheap and mounted on the firewall.

I think Mopar wants ~$150 for the correct one. Might see if the local dealer will let me swap it.

Do you know what the part number is for the reservoir for the manual trans?
