Anyone know off the top of their heads if the GXP has front and rear swaybars?

smartin · « **Reply #1 on:** January 11, 2011, 12:58:27 PM »

Yes, I have DRM's on my NA when he upgraded to the ZOKs.

OK, thanks SM. Someone on the big forum is selling a Z0K front swaybar for a 100 bucks and I couldn't remember off the top of my head if my GXP's had front and rear. I'm always losing out on good deals because they go so quick.

The best handling solution for a GXP is the GXP/Z0K REAR bar, not the front.

I have both and the car works great for me. However I do not Autox with mine.

Hi there!

I have the GXP front bar and GXP Z0K rear bar on my '06 NA. It's very balanced, but tends to have some throttle-on oversteer (which could also be partly due to the factory LSD).

The NA is a far more neutral handler than the GXP (all of the difference in weight is up front on the GXP). Put a GXP Z0K on the front and it will be dead neutral.

Maybe it might be neutral, my car has the Zok suspension and my oversteer and understeer is controlled by the throttle and your speed going into the turn. It also has alot to with camber setting, tires and tire pressure . I do agree that a Gxp front anti sway will improve handling. Snapbob you know your stuff!

GXP bar on rear of NA with stock NA on front not such a good combo, makes them tail happy ask "spinner" I mean Critter. Both GXP bars on an NA is a great setup and cheap.

snaponbob · « **Reply #10 on:** January 18, 2011, 10:24:02 AM »

But he already has the GXP/Z0K rear bar. Why go softer? With a GXP/Z0K front added the car goes neutral, stays flat(est) in corners, and maintains softest ride on rough pavement.

That was more of a trust issue, and experienced Cobra driver said, "you can go through here wide open" so I did. He later said, "guess you needed to lift a bit in the kink".

I now have GXP bars front and rear, and depending on the shock setting it can still be very tail happy, especially in the softer 'street' settings.

How much weight difference between the two?

snaponbob · « **Reply #13 on:** January 18, 2011, 01:20:29 PM »

@ critter - without knowing the alignment it's hard to share thoughts about the handling. However, if you firm up the front shocks that will help some. But, more camber in the back will help more.

@ brazen - assuming both have A/C, about 150-200 pounds more on the GXP.

Dave@DDMworks · « **Reply #14 on:** January 18, 2011, 01:24:25 PM »

Anyone have any interest in sway bars with adjustment to them? They would be the same stiffness as the Z0K bars with 2 adjustment holes in the front and 3 in the back for adjustment and fine tuning. Let me know, thanks!

Critterman · « **Reply #15 on:** January 18, 2011, 01:48:41 PM »

Bob, It is a fairly agressive alignment from DDM, not sure how much negative camber is in it. The stiffer I make the front shocks the less power induced steering, but more understeer. The car balances well if you know how to drive it. The same Cobra driver has shown me that my car on street tires with someone who knows what they are doing is 4 seconds faster the first time he drives it.

The particular incident that goat refers to is a right left kink in the middle of a long straight away that I went through around 6500 rpm, and I should have lifted slighly doing the kink instead of planting my right foot. Leasons learned at around 60 mph the car will come oround quickly. Did a 540 in the center of the track and continued on my merry way. Did lose a lot of time tho.

I've seen those numbers before and always been astounded at the amount. Must all be in the engine, since the rest of the car is so similar (I assume). Anyone know how much the added weight is split between the turbo/piping/intercooler add-ons vs. the heavier duty block?

No real "fix" for over cooking a turn !!!.

The shock adjustments are doing as expected. A LITTLE bit of power understeer is sort of a safety benefit. A LOT of push is a waste, as you said. BTW, what shocks and springs do you have? If I understand it correctly, you have an NA with a GXP front bar and GXP/Z0K rear bar. If so, there is a "free" tweak you can do on the front bar. Drill new holes inboard of the existing holes on the front bar about 3/4"-1" from the existing holes. That will give you a bit extra stiffness to the front bar, but not as much as the heavier GXP/Z0K bar. It is subtle, but it's there. Cost = zero.

I'm running the HKS Hypermax III (8 kgf/mm(450 lbs) front, 6 kgf/mm rear(337 lbs)) shocks and springs. GXP front and rear bars, but could probrably use the GXP-ZOK bars at both ends. I'm pushing 270+ hp at the wheels, 280 torque.

I think the NA with the GXP bar on the back needs the GXP bar up front as well, and with the GXP bar in front you could use the GXP Z0K in back as well, just if you change the back on an NA the front is a bit light, both GXP's would equal NA Z0K's I love the GXP Z0K and stock GXP on my GXP with the same HKS coilovers Critter runs, I have all poly sway bar bushings and it seemed to help a little on the front, at least they don't squeak. The instructor in my car was almost 15 seconds faster than I was, I suck car is great.

Hell yes. Nothing like having 5 wrong combos and 1 correct one. Couple them with adjustable end links (two are enough, one for each end; sealed and quiet ones please). And the most important part - price them low please

I may just skip getting a rear ZOK bar
