Probably best to read from the start, a lot of info is covered on what they are doing and should answer any of your questions.

the answer should be yes on the 21 premium

Note that the crew is still undergoing testing. As of this point they’re going to start testing the Vikings (I wonder if they’re Danes, Norse, Svear, or…?). ?? It will probably be a while before they can qualify and quantify the information they’re gathering. Stay tuned! ??

Heh @scoopman only got about 4K miles on Mach N Cheese’s original tires. They looked to be close to (if not right on) properly inflated based on the wear pattern. ??
Yes, Andy got about 4K from his GTPE Pirelli Summer tires. I took my GTPE Pirelli summer tires off as soon as I got my car and put them on my Premium then sold to my friend. He put 16,000 miles on them (14 months) and they were still in decent shape when he sold them with the wheels. They were inflated to 39 psi and he drives strictly highway. There are several members here getting decent tread life out of them, others not. I know if I had them on my car, I would probably not get anymore than Andy did.

I've been following this thread with interest, and I want to send a big thanks to everyone donating their time and money!

Question: I see a lot of discussion (here and elsewhere) about the "bouncy" ride, and I'm interested to know if this is also what some people might think of as the "harsh" ride. I find that passengers are pretty uncomfortable on our New England bad/patchwork/pot-hole-filled roads in the rear seats of my '22 Prem AWD ER. It's not so much of a continued bounciness after going over a bump, but more like a harsh feeling as if there was almost no rear suspension at all. You feel absolutely everything, and not in a good way. For instance, when I have some cargo in the rear, I can often hear it going airborne when I hit a bump in the road. Would these aftermarket shocks help to absorb better, or is it more about reducing the after-effects (continued bounces) from hitting a bump? Thanks again!

(apologies for the poor terminology, I'm not very informed when it comes to car suspension. I just want it to feel a little more comfortable in the back)

One thing about the Koni's I'd be concerned about is having them on full stiff. Coming from having several sets of coilovers, I've always been instructed to try and avoid the full hard/soft as that causes premature wear...is that a concern you guys would share?

The bounciness is an effect of the dampers not having enough rebound resistance. In a lot of cases, cargo gets airborne not because of the initial compression of the suspension, but because of the quick extension of the suspension followed by the abrupt cessation of the extension (which is what happens with insufficient rebound resistance). I am willing to bet that my Trans Am feels less harsh than a non-Magneride MME over washboard roads, despite the fact that the T/A has metal on Delrin on metal suspension bearings instead of rubber bushings. Its Konis are set to just past medium (although they are from 1979 and need replacement). ??

Not really sure. My Celicas had their Konis set about 7/8 to full firm and I never had an issue. My T/A I mostly run around 5/8 with occasional forays out to full or whatever is necessary for the conditions and they need to be replaced after 40+ years. ?‍♂?

That makes a lot of sense as you've described it. Thanks!! This is a great thread.

One of the things I'm going to suggest is possibly using some poly lube on the Viking/QA1's if one plans to go that route. I have a different set of QA1's on the way TD906's. Same specs as the 903's I had minus the 1 inch spacer that was a nightmare to get off. I'm still fiddling with the Vikings which are nearly identical to QA1's. I'll run my replacement QA1's with the Viking settings I find that cover most of my issues around town. currently 4c/12r which is pretty high on the rebound but I'm pushing it higher over this week. The need for poly lube is only for Viking/QA1's if one chooses to go that route as the polybushing transfer noise to the cabin. (My swaybars are 'groaning' from the grease I used, now going to Follow Mark's note about polybushings.com and just figure it'll help some as well. I'll use a syringe and update in here as to where on the shocks because you don't want to lube the wrong part of it.)

In addition to better the shocks you're all working with. Thanks so much.
Would the rear springs from a regular battery work in an extended battery car?
I know the gt springs offer changes. I wasn't looking to lower the car. We almost never have passengers or cary significant weight.

I would think that just changing the rear springs to a lower rate would imbalance the car. If you're going to do that, you should probably swap both the fronts and the rears. You still might have an imbalance, but less of one. Since the ER battery adds more weight to the rear than to the front, the rear spprings would have a lower rate than the ER rear springs and the front springs would have less rate than the ER front springs, but the percentage difference between spring rates would be larger for the rear springs. I don't honestly know the spring rates for the different battery/drive combinations, so that's just an educated guess. ??
