Brian,

How much wheel/tire would you think someone would need to be running before the Club Race coilovers are worthwhile over the CRDs? Are we talking only on a car with 17x9 or 17x10 wheels and 245/255 width 200 TW tires, or would they also work well on something a little more modest like 16x8 or 17x8 with 225 PS4s, ECS, or something along those lines?

Even with 17x9 the roll resistance gains from the higher spring rate will be evident in autocross/track use. But with 17x8 the 7/5 combo is plenty.

It has been a long time, I would need a more side by side to give meaningful comparison of the FEAL and MeisterR.

When did your spec Feal come out, and how was it developed?

Ran those in another project NC here, found the thread but not a lot of comment....link HERE.

Since it was two years ago, I just don't recall a lot of detail now on those, and two pages later I am talking about how much I love the OHLINS in that NC at Laguna.

Thanks Brian, I am going to ask Odi to see what he knows/remembers.

I'd also like to see more on the FEALs since I just purchased a set of 441+ Road Race coils from you. :wink:

That triple pass GWR radiator looks like definite overkill for a relatively mild 2.5 build. You planning a new supercharger option to test on this one?

Not overkill for a car that we actually autocross and track, weather gets hot here, events often have over 100 F ambient. Prior normally aspirated "Project Blue" 2.5 conversion compromised a perfectly good 2.5 motor on hot autocross day here ...without boost.

Nonetheless, we are considering testing new turbo kit on this project that is on the way to market by this Summer. If so, will be doing a lot more on cooling, including E85 and vented hood, etc.
