Installed drag bags today

For those who are anxious to know if they eliminated the wheel hop let me say, "Hell yeah they did!" Man what a BIG difference! I have never been able to spin the tires with so little effort. The wheel hop is totally gone. Maybe the drag bags combined with the Pedders rear drag springs is why. So I'm not sure how well they will work with the stock springs. But anyway. The install wasn't too bad. The hardest part of the job was getting the bags into the springs through the coils. Those Pedders are stiff as hell so that wasn't too easy to do. Once I compressed the bag enough and got the majority of it through the widest opened coil, I spray the coil and bag with some silicon spray and it slipped right in. The bags fit perfect in the Pedders. The kit comes with 2 valve stems and a tee which connects both line from the bags. Only one valve stem is needed because of the tee. Maybe the kit just have a extra one in it. The instructions say to drill the rear valance and mount the valve stem on it. I didn't do that. I just drilled a small hole through the trunk and mounted the valve stem there. It's totally out of sight and the kit comes with small rubber washers that will keep water from leaking into the trunk. So with my small portable air compressor, I can just air up the bags at the track, from inside the trunk, without anyone knowing. At 25 psi, the rear is jacked up pretty high. I lowered the pressure to 15 psi and hit the streets. 15 psi seems to be perfect. Like I said, the tires spun with ease with no wheel hop at all. Plus the ride isn't compromised by the bags being at 15 psi. The instructions recommend 0 - 20 psi for normal street driving and 25 psi for drag racing. At 25 psi you can definitely put wider wheels and tires on with no rubbing issues. Below are some pics I took after the install. Like an idiot I didn't think of taking the pics while the rear was up on jacks. Oh well, they still came out okay. Enjoy!

Wouldn't they be counter-productive to gaining traction at the track since they are going to keep the weight transfer from getting back the way it should.

Maybe my thinking is backwards.

Good point. But remember you can adjust the pressure from 0 pressure to as high as 25 psi MAX until you find the sweet spot. Then once you do, that's when you throw on a set of drag radials and really have some fun.

Also, I was dropping the hammer around 4000+ rpms. I would never drop it that high at the track. Normally I'm between 1500 to 2000 rpms. Plus I have a 6 speed which really take some practice for a good launch.

I did take off the springs. It's just that the Pedders springs are shorter and a bit thicker in diameter than the stock ones. So compressing the bags enough to get them through the coils was a PITA. But well worth it ($99 shipped to my door).

Haven't gotten the Maggie yet. It should be shipped next week. My JBA mid pipes with high flow cats is scheduled to be delivered on Sept 15th. Hopefully the supercharger will get here around the same time. I hope I can have all mods installed and ready for the dyno tune by Sept. 23th.

The ride height wasn't affected.
