Hi, anyone planning to use R-springs from FP or aftermarket for track use? I believe R's are stiffer and ~1/2" shorter in front. BTW on MR.

ArizonaBOSS said:The stiffer front rate (and resulting understeer) could be compensated with a stiffer rear bar; but you may be giving up overall grip in exchange for balance.
You're welcome. ;D Have you seen the new Star Wars movie yet?steveespo said:I am personally in a bad place, the pull of the S550 is strong and the GT 350 even stronger. A sale of the original 21 car is being contemplated.

steveespo said:Drew is correct. To improve grip and balance should look to aero improvements up front to go along with stiffer and lower springs. Killing grip in the rear does just that kills grip in the rear and makes a car snappy loose. I would upgrade to R spec on everything, splitter, wing and springs. Wheels yes but not the CF wheels, a more affordable alternative is being made by a vendor here on the site.

I'll never forget him saying "I love this car" at Road America after repairing the rear end troubles. But hey, that's what memories are for!superhero said:I have one thing to add....Don't do it!
This is just my opion and we all know about them.
the 21 is something special that is apart of your blood.
Hell on a fresh set of sticky tires you will hang with the 350.
Never! As soon as my car is produced I'll start the mod process.Tob said:If Ford Racing releases a spring set I'll be doing it. I'd like to dial out that small percentage of compromise that had to be included in order to meet certain internal engineering standards at Ford. If the 6GR wheels hit the mark those will be going on to with R sized rubber.
Never ends, does it?
Cool when are you installing?VoodooBOSS said:The R springs are available on ebay. The part numbers are as follows:
FR3Z-5560-P & FR3Z-5560-T Left and Right Rear Springs
