Anyone feel ok about running these??

No listed springs rates = no buy.
Would you buy valve springs with no listed specs on them? How would you know how well they will work with your setup?

Critical engine part vs suspension part that isn't going to really harm anything = horrible comparison.

That said, no, I wouldn't run them.

I ordered the Vogtland springs, German made and are a legit manufacturer.

Same idea. Both are springs that have specific rates that will depict how well they will work.

those Chinese springs look cute but it only takes 1 of them to sag or let go. Keep an eye out for the Vogtland on Ebay, a full set will vary in price from $175 - $200. that is cheap! They are cheaper than Eibach and H&R. And Strano private labels the German made Vogtland built to his own specs, and I'd trust his opinion on F-Body suspension before any Chinese Ebay vendor.

Not trying to defend the seller, but they have that listed.

If you want something little cheaper then get the Vogtland springs or get a used set of bmr and so forth

****, sorry dont know how I missed that.
In that case, are you setting up a drift car? Because those rates scream heavy oversteer.
350lbs/in front is WAY soft, softer than any lowering spring that I know of. Factory 1LE springs (stock height) are even stiffer at 360lbs/in. Most lowering springs at that height are 500+lbs/in rate.
For the rear thats generally stiffer than any aftermarket spring out there, popular/proven setups for the rear are around 150lbs/in (and that a HUGE difference because of the solid axle and less weight we have in the rear of these cars.
If all you are looking to do is lower the car cheaply, you are better off cutting the stock springs than buying these.
