Seat leon fr mk3.5 brake upgrade

[Dodo07]

I'd like to enlarge the brake discs on my 2020 Seat Leon FR 1.5 TSI MK3.5. I'd like to change the OEM 288 front and 253 rear discs to 312 front and 272 rear discs. Can I purchase these directly, or is there anything else I need to do? Can anyone with information on this matter help me?

You'll need new brackets for the calipers, to reposition them for the larger discs, plus of course the discs.

Everything you need ought to be available from the VAG parts bin.

I did a similar conversation some years ago on a Skoda Yeti replacing 288mm front discs with 312mm ones listed for the Octavia vRS.

What are the part codes of the caliper brackets I need or which ones are used in which vehicles?

Sorry; no idea on that.

I don't have access to the relevant information.

Remember that the braking efficiency of the car altimately depends on how well the tyres grip the road. No point fitting larger brakes if the tyres have low grip.

The other day I walked past an A3 1.5 TSi with obviously not standard enormous brakes but with cheap tyres with what looked like just about legal tread depth. At least it looked good, but I wouldn't want to drive it on a wet road.

Aracın frenleme verimliliğinin büyük ölçüde lastiklerin yola ne kadar iyi tutunduğuna bağlı olduğunu unutmayın. Lastiklerin yol tutuşu düşükse, daha büyük frenler takmanın bir anlamı yoktur.

Geçen gün, standart devasa frenlere sahip olmayan, ancak diş derinliği neredeyse yasal olan ucuz lastiklere sahip bir A3 1.5 TSi'nin yanından geçtim. En azından iyi görünüyordu, ama ıslak yolda kullanmak istemezdim.

I agree with you on this one. Without good tires, everything else is meaningless. I have no problems with my tires. I installed Continental Premium Contact 7 a few months ago. I really like my brakes, but I know they could be better, so I want to see how far I can go without changing my calipers.
