Only bad thing I can say about APR is they're not doing Volvos; seriously? A 2.5 transverse engine using a haldex system to get it to the ground.... On the surface it sounds so similar.... Really wish some of APR's products were available for a Volvo.
APR really has some Nice stuff for the CC also , but choosing the $300K Fully Custom
Polestar S60R would be a Hands Down Winner . I don't think one will be available for 60K Thou .
( Man I'd like to see those 2 Cars do some Track Time . )
The Audi TTRS - 5 cly is one sweet Motor and Audi took it a few notches above the Volvo - RS . Considering Volvo RS was out First , Plus
Audi/VW has the Bosch Manufacturing Development just about all to themselves.
As Far as Future research goes , Volvo did NOT have Direct Injection for the Motor
on Their Radar - Not to mention Volvo as a Company was up for Sale .
The DI alone allows 35HP more in Basic Motor set up .
