Please help me with this as my tyre's are constantly rubbing the arches over bumps in the road. Specifically I am trying to find any information on the 'rough road' specs for the C5 Quattro. Also with regards to the weight ranges / categories am I right in assuming the higher the number or alphabetic letters e.g. DQ the more weight that component can take.
What wheels do you have please ?
Width , diameter and offset (et) ??
What tyres please ??
Width , diameter and aspect ratio please ?
I have lowered suspension with 235’s on 18’s and there is plenty of clearance !!
You have just answered your own question !!
You are running the wrong size tyres , the fuel cap numbers will give you the size you need to match from , if you have not got 18’s on your fuel cap then you would need different suspension uprights to accommodate them ,
So looking at the fuel cap sticker tells us everything !!
I don’t need to look at it , I can tell you your non standard set up is not compatible !
It’s not rocket science , leave your suspension alone and fit the right size tyres !!
Couchie, its called modifying. A small increase in height will fix the issue and provide a better set up for my **** local roads. Reducing the aspect ratio will get me round one issue but cause exactly what I am trying to avoid as there will be no flex in the sidewall. The original question was to do with spring rates.
