Do the Nitrons really require servicing as they suggest? I can't find the documentation, but they said every 12 track days or something like that they should be sent in for a rebuild. I have probably 25 or so on the clubsports and they seem fine. Is there a symptom I should look for?

Hethelsport in the US has them

I really want to try the Eagle f1 Supercar 3Rs as everyone rages about them, but they do not have an XL rating for our rear sizes (2017 400). Would I be ok with the SL rated rear? Would it stand up to aggressive track use? I know one forum user in the US running them and he loves them.

Circling back to this. On track, the Nitron suggested setting of +10 clicks front and rear work great. I have 5 track days on the books with them and the car has never handled better (less roll, more stable, easy to correct, etc.) I played with +15 clicks which is closer to stock if not even more subtle on the bumps since there is less unsprung weight. I have never had an inertia switch issue and found out that the original friend of mine that did was using a pervious owners Nitrons and the bumper stops were missing, so the root cause may be lying in that somewhere.

btw, the Cup 2 Connects wear very well. I got at least 6 track days in so far with no edge wear. I have a second set ready to go in, but my next tire after that will be the Goodyear F1 Supercar 3R. They have gotten rave reviews in print and from track peers.

I recommend kicking the habit on a track focused car. I once put it on very carefully and waited a full day before driving. The following day, it still spun to the outer driving area of the tire. I scrubbed it all off before track day.

Wish to minimize the body roll in turns. Especially in the S's where I am transitioning quickly.

Yes, but I bought through GRP, some of the website descriptions and pics differ but mine were delivered with 625 lb/in springs in rear and 425 up front. all four have 250 lb/in helper springs which are fully compressed once installed. I am a little concerned about being too stiff. A friend had these and liked them on track but the interia switches cut off the fuel three times in two years. As a side note, everyone should know where these are to reset them (button press) and its not advertised.

I am mid install of the Nitron Club Sports on a 400 that sees ~10+ track days a year. I also have race ARB bushings on the ready. Do you suggest I wait on the ARBs? Do they make the clunking worse?

Just seeing this thread now as I am mid install of my Nitron Club Sports on an Evora 400. I hope Nitron has sorted things out. The manufacture date was 2022 so fingers crossed 👍.

Did you see a difference in tire wear though? Did you track many times with each setting?

Also, can anyone share a track alignment that they are happy with? (stock suspension only please) I plan to have my performance indy shop do the work, not my Lotus dealer. The car is weekend only and will see 6-10 sessions per year. I am concerned with track focused performance. The tracks I go to have me no more than 200kph/125 mph with some faster 160kph/100 mph turns as well as technical twisties. Thanks.
