Regarding the JHM rotor upgrade.

[sempdog]

I'm looking forward to testing out these new products by JHM. My question for them is:
"will I be able to fit an 18 inch rim over these larger rotors? For track purposes."
Or will we need to retain the stock 19 inch
Thanks

Check out JHM's pole regarding which wheel color to go with on their shop RS4. I believe they have selected an 18" wheel and they have the larger l/w rotors installed. When in doubt, call them directly and ask.

See if they can provide a printable template to check. StopTech used to do this.

Unless you can find an 18 with the right offset and a big enough barrel diameter you are going to need to run 19s or bigger. I tested and made sure the 380 kit was good to go on my car then took it off and sold it to another customer, the only reason I did this was to run 18s. We also had a used set of our 365 rotors on the shelf from a customer complaining about vibration with them(Our shop cars always get the old/worn out stuff ;) ). Well after I installed them I bedded them in properly and they are good to go.

The 18s I am going to order may in fact clear our 380 kit but I really don't know at the moment. We made the kit as a minor upgrade over stock and because people wanted it. A lot of guys will never run anything other then 19s or larger on their rs4 so this is really not a concern for some.


18s or larger you can run our 365mm lightweight performance replacement rings:

19s or larger you can run our 380mm kit:

Let me know if you have anymore questions

Worst case scenario, run a small spacer. 3-5mm should be enough to gain clearance over the calipers if they are too big, and should not make any difference in your ride quality/performance on the street or at the track...

I tried a friends Team Dynamics Motorsport Pro Race 1.2 18x9 w/ a 20mm ET, and they fit my car running a Brembo 380mm Big Brake rotor and OEM RS4 calipers.
