Firm feel ISO delete

shout out to Matt and Dennis at Firm Feel.
My factory ISO plate/bracket split apart over the weekend. Damn the Midwest and all its rust.
Was able to get a ISO delete kit on order early this morning. Hopefully, my Fifth Ave is back on the road by the weekend. Great customer service and I’m ok with the price. Better than another set of U/channel style plates and isolators to trap water.

I feel your pain with the rust! Gotta love that road salt or worse, that liquid crap they spray.

The ISO was good for hiding broken springs.

I'm hoping to have my Iso delete stuff installed within the next couple weeks as well, and I agree..the guys at FFI are great to deal with. Quick turnaround too.

Ordered my ISO delete Monday the 13th, got it Friday morning the 17th. Started in on drums, shoes, wheel cylinders shocks and the ISO delete around 2pm. Pulled out of the garage at 11:58pm and went for a cruise. ISO kit made a huge difference in handling and looks like it raised my rear end up about .25” or so; Enough I’m not smacking my mufflers pulling in and out of my garage anymore.
Again, huge shout out to the guys at Firm Feel. Don’t hesitate to place an order.

Deletion of the ISO-Clamp system will raise the car the thickness of the upper rubber mount, which is roughly 3/8” (7 mm) if using FFI's kit, or closer to 1/2” (12 mm) if using the older design shock plate.

Camtron do you have any pictures of the set up installed?

@picklesgarage, for me, it’s just their FMJ bottom plate and Ubolts. The kit comes with sway bar brackets too but, I haven’t got a rear sway bar.

Correct

If you need to replace the rear shocks – I would use the FFI B-body ISO-Delete kit over the FFI FMJ ISO-Delete kit. The money to FFI is the same and a few more options with B-body shocks over FMJ shocks.

The FMJ shock plate is still in use and can barely be seen in the above picture. It is sandwiched between the differential perch and leaf spring.
I really dislike working on FMJ lower shock studs (a huge pain in da ___) so ditching the rear (lower) stud is a big plus. Also, if a person plans on using air shocks or spring-assisted rear shocks – I don’t think the (original) FMJ shock plate will hold up long term (or even short term) – but that is my opinion only. Leaving the FMJ shock plate in place looks goofy and over complicated vs. the older shock plate (or FFI’s B-body ISO-Delete kit).
