Suspension Help needed...
Hello, & Thank's for coming in and offering advice ! My Problem ? I need to eliminate a serious case of wheel hop at the drag strip. My '99 FRC just blows the tire away in 1st & 2nd, and it even wheel hops in 3rd ! I am running a DTE rearend girdle, DTE 4.10's, and Nitto 555's. In it's current state of tune, my car is making 389 rwhp/380 rwtq.

Wow wish I could help. I've been around here a pretty long time and not seen any conclusive moves to eliminate wheel hop. All I can share is my experience.
I had a stock '01 FE1 and until recently a stock '04 FE1 suspension. Both had wheel hop. On the '04 I've recently gone to Z06 springs and bilsteins and wheelhop seems gone.
I have stock MN6 gears, putting down ~320 on Kuhmo MXx, 295s. So, with this setup, the springs/shocks/Kuhmos work well.
But honestly, with my near stock power and the 295s out back, I get very little wheelspin anymore if any, so I have no idea at all whether this will help.
Also, I noticed a significant reduction in squat upon acceleration, so in the end this may hurt drag racing times. Don't know.
Sorry for the long reply, hopefully something I said helps.

Try lowering it some, My car doesnt wheel hop, I lowered it 2" and put Blistiens on and It hasnt done it, but then again that was one of my very first mods. Just my 2 cents. Maybe this will help. Good Luck!

Thank's Fella's...
My Buddy (99theHardWay) had suggested this as a possible remedy, as he is in the same boat as I ! That would be an option for him, however, I am running a 295/45/18 tire on the rear, so unless I buy some new, stock size tires, I don't have room to lower the car. I was wondering if anybody knows of a stiffer ratio rear spring ? Or possibly, does anyone out there manufacture a set of shocks for drag racing C5's, like the old 90/10's you uesd to be able to buy ? Thank's,
Steve.

Different bushing's ?
Hey Guy's, & "Thank's" for the input !
I haven't seen any discussions about changing bushings as a possible remedy, does anybody out there have before & after experience with this ? Steve.

Thank's Klem....
Klem, thank's for the input, I also forgot to mention that my car has "Active Handling" so I don't know if I can actually swap in some adjustable shocks, even though that appears to be my next step in an attempt to eliminate this problem ! i was on TBryne's website, and saw a nice set of adjustable shocks for what seemed a good price. My buddy has an '01 Z and he is making the same HP, and he did just install a set of Bilstein HD shocks, and he still experienced the same problem with massive amounts of wheel hop.

Thank's for the info....
Thank You Clem, I will give him a call in the next day or so ! I am wanting to hit the track again this weekend, however, until I get this figured out, I am not going to run the car & risk breaking something ! Later....
