Great engine that you picked; congrats! As for the question above -- I'm not a fan of Bridgestone RFT with 20 inch wheel option and non-sport suspension. Tires seem to deflect on certain impacts instead of being compliant, and high unsprung weight of the 20 inch wheel coupled with non-sport shock tuning is an odd combo. Seems like damping was optimized for something less than a 20 inch wheel. Running 18" wheels with narrow non-rft winter tires now and much happier wiuth the E70 suspension. By comparsion my 4.8is suspension feels dialed, even with the weighty 20's.
