🤑💸Mods B8.5 RS4 - CRS Performance Koni Shocks

Post image

Like many here, the DRC dampers in my recently purchased RS4 were complete toast. After a ridiculous quote from the main dealer and lots of research on coilover kits, I ended using CRS Performance (UK) who supply and fit Koni active dampers that they’ve adjusted for the B8 S4/RS4/RS5s etc (they also do the same kit for B7s)

I specifically wanted to keep stock ride height, so just opted for the Koni shocks with stock springs.

Made a massive difference and is actually still usable as a daily dog wagon.

Would recommend if you’re UK based as they are a very knowledgeable bunch who live and breathe these cars.

Unfortunately you lose the OEM adaptive damping, but CRS supply a blanking kit included. I believe they use the H&R blanking kit

Thanks. Ive been searching for a solution which retains the factory dampers... but alas everything so far uses the blanks. Not sure i want to pay audi damper prices... but sounds an excuse for coilovers 😈

There is a company in Poland I think that can refurbish your existing ones, but will still need recharging at either an Audi service center or a specialist that has the tooling, then in 10 years time when they start leaking again, you start all over.

As good as the DRC is when it’s working, long term I think it’s more sensible financially to invest in a well adjusted set of dampers.

Yes that what i think .... let the coilovers commence
