Why does the rear end bounce up and down so dramatically under hard acceleration? Any way to reduce this or even eliminate it? Does this hurt help or anything at all to the performance? :rofl:
SLP sway bar $139.00, poly end links $34.95, and Harrop rear subframe poly bushings for $149.00. This combination isn't expensive and will definetly reduce wheel hop (85-90%)!! Good thing is I stock everything but subframe bushings which I will get in about a week and a half. :cheersbadtmpdgoat said:Why does the rear end bounce up and down so dramatically under hard acceleration?

Interesting, you have ALL of the mentioned parts, including the subframe urethane bushings? :confusedGTO_Newbie said:On the street, the mods mentioned seem to reduce a majority of the wheelhop. With drag radials at the strip, the wheelhop was as bad as ever. If I had stock tires, it wouldn't have been so bad cause I would have been spinning more.
I put adjustable shocks in this weekend to stiffen the rear end to control the pogo effect. Hope to have some reports shortly.
Here is what it was like, even after all the mentioned mods, with drag radials on a nice sticky track, but before the rear shocks.

I know this may sound crazy, but, try going to a 275/40/17 drag radial (I used the new Mickey Thompson), for some reason I had a ton of wheel hop with the Nitto's in a 245/45/17 and when I switched to the different tire and size it stopped (with above mentioned mods). :cheersGTO_Newbie said:SLP rear swaybar

Did you notice a change in traction? My plan is to try out a firmer shock and launching at a higher rpm, if the weather clears I'll try it tomorrow night.GTODEALER said:I know this may sound crazy, but, try going to a 275/40/17 drag radial (I used the new Mickey Thompson), for some reason I had a ton of wheel hop with the Nitto's in a 245/45/17 and when I switched to the different tire and size it stopped (with above mentioned mods). :cheers
HUGE improvment in traction!!!! I sell the QA1 adjustable shock kit for the GTO's along with the entire BMR line call me and I'll go over pricing!! :cheersGTO_Newbie said:Did you notice a change in traction?

Already setup on the BMR and shocks - just awaiting a track to test them, works great for the street with the Nittos :cheersGTODEALER said:HUGE improvment in traction!!!! I sell the QA1 adjustable shock kit for the GTO's along with the entire BMR line call me and I'll go over pricing!! :cheers
I still don't think anyone addressed SQUAT (pun intended!) under acceleration. I won't be drag racing my GTO but that squat is really annoying when I blast away from a light. What can remedy this? Also has anyone replaced their gauge covers with color matched ones from Arrowhead or anyone else? And finally-shifter and cold air induction-where can I get them?badtmpdgoat said:squat,,,under hard accel. I see a driver behind me then bumper tjhen driver,,every hard shift,,, :lol:
Okay, I'm starting to feel inadequate here: I've never experienced wheel hop, so I take that to mean that I must not be accelerating hard enough. I don't drag race the car, though. I've never been on a drag strip in my life. I just like to make the most of every opportunity I have when I'm first in line at a stoplight.sandlakeont said:you mean to say that every time you nail it from a standstill you get this wheel hop?
I must be blind because I can't find where to order from youGTODEALER said:SLP sway bar $139.00, poly end links $34.95, and Harrop rear subframe poly bushings for $149.00.
