Those are the RS3 rates, not the S3...would make the assumption (have not seen/found specific S3 rates) that the S3 front rate is near identical to the R and the rear is slightly stiffer rear. S3 is roughly 150 ish heavier overall than the R (3330 ish), most of which is on the rear axle and the RS3 (3650+) is another 150 lbs on top of the S3 (3450) , mostly on the front axle. But feel free to post if you have a source stating otherwise...
S3 rates would'nt be worth the time and/or money to install them. 034, neuspeed, RS3, (stockish height, minimal drop, but an actually increased rates) on the other hand could be depending what the motivation for modification is. I am sure stock shocks will work, but not ideal, if you are going through the pain of a spring swap. I would recommend people interested save themselves the ass pain or money of doing it twice and put in B6s( stock to 10mm lower) or B8s (15mm lower or more) depending on preference, better strut mounts, new bearings, etc.
Golf R fronts are 215, 190-ish is the gti front rate. According to APR, before their website became the new mess it currently is...but found the data page here.

It's why the eibach's primarily suck as an option (170 ish front), and much better exist, IMO. People who have stated on the forum, they made the car "feel stiffer" and "handle better" on the eibach's, makes my eyebrows raise, and my BS filter trigger when the front is most highly riding the bump stops through corners and crashing into them into submission on normal road bumps.
Highly doubt eibach did any actual testing on Rs, or S3, as the part number is identical to the gti, beyond, yep the spring we designed for mqb GTIs fit, good enough, full send it, no R&D required, print $$$$$$$$$$$$. Feel free to correct if you find other information, eibach has good stuff, just generally their pro kit springs for VW/audi are highly questionable at best for the R, S3 variety. Probably great on a regular golf, marginal gti, and generally unsat on Rs...as real world forum wisdom seems to be indicating.
Depending on what the intent for the car is, imo, front and rear sways are a better first upgrade handling upgrade(combined with a zero toe rear alignment) on a stock R, before you throw springs at it. Unless wheel gap aesthetic, not improved handling performance is you're primary motivator for springs.
