Here’s a list of posts and DIYs that should help any P2 R owner, from fluid questions to which tires to buy. Use it to compare your P2 R ownership experience. While I wrote about owning an R car when I did, much of the material linked to from this post was written by other owners. As always, thanks to those who have shared what they know.
By definition (“P2?), this guide covers Volvo R cars from 2004-2007 model years. The other R cars are the earlier generation P80 platform. Anything else is the looks-only “R-Design” trim option offered on C30 and XC60s.
I bought a 2004 V70 R in 2010, and I needed to “baseline” it, get it back to Stage 0. I wanted it to drive like it came right out of the Ghent, Belgium factory like it did in July 2003. After the 90k service listed below, I gave her some Seafoam and new tires.
