Brakes too good to be true for the price?

Hey guys, looking to replace my front brake rotors and after some search I found this set

https://www.elise-shop.com/eliseshopcom-308mm-brake-discs-incl-bells-elise-s2s3-exige-s2-2eleven-p-524688.html.

Compared to other ring rotors even without the fixed hubs are some times half the price.
Any one tried this set?
Is there a catch?
I understand that there are different quality of rotors and brake sets out there but will a cheaper set or rotors like this make a difference on the road than the AP Racing set or Alcon?

P.S My car is only driven on the road and never on truck

Cheers everyone.

You mention that this is only for road use. What issues have you had with the standard setup.
Normal upgrade route would be to change pads to something more aggressive, add braided hoses.
Would expect that to be enough for road use, and a move to 308 and belled discs would be for asthetics rather than performance unless using on track.

Agreed. They will look nice and lighten your wallet but for road use they are over kill.

I fitted Ultimax disks and Pagid pads, they are more than sufficient.

I 100% agree that the stock brakes with upgraded pads are just fine but the car is heavily turbocharged and modified and a lot more powerful than stock.
I do not track the car but I do push the car on country back roads and mountain roads and I would like to have the peace of mind that I would not run out of brakes.
The car is already upgraded with Alcon 308 disks and Nitro hubs.
The problem now gets a bit complicated . The hubs I got are 177.8 mm PDC, all the replacement 308mm rotor rings I can find including the AP that Lotus uses are 190.5mm.
So far the only ones I can get with the correct specs are the replacement Alcons and those come at almost 700 pounds just for the rings,
Unless there is a significant difference between the Alcon rotors and the ones I linked earlier I don’t see why I should spent twice the money for the Alcons.
In what ways can a cheaper rotor and hub be of lower quality than a well known manufacturer?

Things to consider would include the operational life of the disk. How much wear before it is deemed to be end of live.
Design with respect to cooling efficiency. Resistance to thermal loads, you wouldn’t want the disk warping or having issues with pad transfer that result in it having to be scrapped. Having said that I’m pretty sure you would be fine with EliseParts or EliseShop disks if you are only using it on the road. However not going to make any recommendations regarding a safety critical part, you need to make your own decision.

Would also say that from my use I have preferred the Alcon discs to AP. They seem to have stood up to track abuse better. AP discs seemed to wear prematurely and certainly for drilled discs had issues with hairline cracks.
