Just keep in mind that wheel spacers are not safe. I have seen them break and I believe the NHRA has disallowed them. I know the local track will not let you make a pass with spacers installed. your track may be different.

For the way Popo uses his cars, I don't think spacers will be an issue. If he was out road racing or trying to launch it at the strip the that big of a spacer would be a little sketchy, but as long as they're hub centric i'd bet he won't have any problems with normal driving. I ran my car at Grattan with 15mm on my rears and they didn't have any issue with it. Some ARP studs would worth the peace of mind for how cheap they are.

OK, I just felt it needed to be mentioned. I use to have a video of a spacer breaking mid track, It was quite ugly! I lost the link when my puter crashed, so I cant post it.
I know Popo does run it hard at the shootout, so I felt like I should say something. good luck!

NHRA 2017 General Regulations - Section 20, page 31 - 5:2 WHEELS:
Wheel spacer permitted. Spacer to be either hub-centric or lug-centric and must fit with minimal clearance to retain concentricity. The wheel spacer must not reduce minimum permitted thread engagement below the limits established by fastener diameter. (see example as stated above.) No stacking of wheel spacers allowed.SOLD - GONE TO A (VERY) GOOD HOME ! - 94 Formula A3+1: 381ci forged stroker - Callies Stealth, Oliver 5.85 billet rods, BME nitrous pistons / CNC LT4 heads / CC solid roller / TH400+GearVendors OD / 4.11 Strange 12-bolt / 300-shot N2O / Spohn Suspension / roll bar / MoTeC M48 Pro engine management system /a few other odds 'n ends.

That said, I would be VERY careful regarding the source of the adapters. There are shops out there that make high quality, billet 6061 T6 aluminum adapters. There are shops that sell cheap Chinese junk. Look for references, particularly for shops that focus on activities like off-roading, rock climbing, etc.. Used to deal with a shop called Skulte Designs, but he is no longer in business.
I would recommend upgrading the stock lugs to a quality-sourced, high strength steel lug. Ensure that the secondary lugs on the adapter are high strength.
If you are going hub-centric, the Impala SS wheel is 78.3mm, according to this source:
https://www.wheel-size.com/size/chevrolet/impala/1996/
I have seen a table from an adapter manufacturer that shows it as 78.1mm.
For hub-centric, Larry will also have to check the hub hole diameter on the repro C5 wheels. Things get complicated because of the differing front and rear hub diameters on the 93-96 F-Bodies. Typically, the 93-96 hub holes were made large enough to fit over the larger rear hubs, making the front wheel fitment lug-centric. 97 and up, the rear axle hubs were reduced in size to match the front hubs. Who knows what diameter the aftermarket wheels use? Gotta measure.
For the install, a quality torque wrench should be used, following the adapter manufacturer's recommendations, star pattern, multiple passes, yada yada.SOLD - GONE TO A (VERY) GOOD HOME ! - 94 Formula A3+1: 381ci forged stroker - Callies Stealth, Oliver 5.85 billet rods, BME nitrous pistons / CNC LT4 heads / CC solid roller / TH400+GearVendors OD / 4.11 Strange 12-bolt / 300-shot N2O / Spohn Suspension / roll bar / MoTeC M48 Pro engine management system /a few other odds 'n ends.

Supporting Memberand change wheel studs to arp, along with the adapter studs should have arp studs as well, especially anything over 1.5" thick

Im no stranger to spacers... just tryin to figure out how to get the right ones.
Gonna put this on hold till I can get the car level as its leaning a bit to the front right, raising the left rear. Had an alignment done, and that made it a bit better. Hoping the left rear lowering spring just needs some more settle time. Will also be checking all the other springs and mounts to make sure nothing shifter or broke.
Our cherokee had 3" spacers... the 95 camaro had 2" spacers on the rear and the camaro and impala have 1/4" spacers with extended arp studs as well...
