cartridge kits for Showa BPF

My V4 base is a trackbike, my shock is a Ohlins TTXGP and now I'm looking for a upgrade in the front. I'm quite pleased with the Showa but I'm looking for the inserts from Ohlins. I knew of the NIX30 (FGK229) and also found the TTX25 (FKR115), the second one a lot more expensive.
Can you guys who have done these mods give some feedback if it's worth to change. I do only trackdays (too old for racing now) but still expert level and 10s of the laprecord on my hometrack. Thanks,

If your home circuit is the Isle of Mann, then that's pretty good going. If it's somewhere else, and the lap record is 29 seconds, then not so good

I have the andreani cartridges in mine. V2 but, same forks. Much cheaper than ohlins, same quality and I love them. Huge, significant upgrade in the handling of the bike. I was maxed out on adjustability for the OEM and these opened up an entire new door. A level as well, less than 10 seconds off lap record.

Yes, your wright RickD996 , doesn't say much .The track is Zolder and it's 4,3km long. I just wanted to give an idea of my pace because I know to feel the differents of the upgrade you need to be fast enough.
I'm not sure if that's the case. I don't won't to upgrade just for the fun of it. The Showa is OK but i can't persuade myself to push the front because I lack confidents.

Realistically, upgraded cartridge kits do not suddenly open up a whole new world of feel. What they do give you, is more control and adjustment. If you can get your stock forks to within 5-10% feel of what you're looking for, then upgrades will get you the final 5%. It's unlikely to make much difference to your lap times.

Some people upgraded, and then start adjustment/tuning, and say the difference is amazing. But, from my experience, if you set up good stock kit first, there's not huge differences.

Going to different technology (ie through rod, or gas pressurized), you'll feel a difference. That feel may help you enjoy the ride more, but if you're cracking on on stock kit, unlikely to effect lap times.

My pb at Donington Park GP circuit is four seconds off the lap record (1:30.0 record), on a Kawasaki ZX10R with 100% stock fork, brake discs, calipers and master cylinder. Those forks are epic though

Thanks, Rick. I leaning to upgrade to the FKR cartridge. Do you have experience with these. I see in another post you're using Mupo now. Do you like them?

Many moons ago I had the FKR cartridges in an S1000RR, I wasn't overly enamered by them. With my riding style, ergonomics and setup, I find Ohlins generally 'wooden', or lacking in feel. I find K-tech very very direct and detailed, Bitubo very smooth (you really really need to push on them to get 'feel', but it is there), the Mupo CSP is in-between the Bitubo and K-tech. I really want to try Maxton, but that's because the owner of the company is very hands on, and will come and spend time with you at a track, giving one on one setup help. No other manufacturer offers that, and I've never heard bad things about their kit.

The reality is, you need to try the stuff yourself, find what suits you. Unfortunately, that's a fairly expensive process!

K-tech offer good support directly from the factory, literally just call the UK office, and ask for setup advice, brilliant. I would probably start with them, if I was starting my trackday journey again. But, it's all personal preference.

Bitubo pretty much make the best shock though, actually will make the bike drive better than an Ohlins.
