Anyone tried ns2r on a heavy car?
Discussion
I’ve put some ns2r on the front of my c63 to save my mps4s on the odd trackday. They grip well for about 3 corners then squeal like hell and understeer! So much understeer I can’t back it in. Only power oversteer.
Dropped pressures from 38 to 29 cold which was a slight improvement but it still sucks.
I wonder if they just don’t work on heavy cars or perhaps there is any advice to get them working?

Actually the experience is now similar to the budget tyres in this vid.
Time to ditch and put some cups on I think.

What are you running on the rear and what compound of NS2R are you running? The 180 “street” compound doesn’t have the most grip but it’s consistent and holds up well. The softer compounds are grippier.
Sounds like it’s overworking the fronts very quickly so I wonder if you’ve got an excess of rear grip compared to the front tyres.

Ah, 180 tread-wear is the street/hard compound, 120 is medium and I believe they do (or did) an 80 in some fitments.
You won't find them the grippiest by any means, but they should be consistent. I do think a drop in pressure will help them as IIRC they work better at lower pressures on track.
I liked them for the price, but this was a good few years back when they were a conspicuous bargain.

I've run Conti Sport contact 3 and 5 as well as the NS2R 180 compound for a few years now. Same car setup, same track (the local shakedown spot).
Im terms of lap times there is almost no difference (not timed competitively but done enough laps with a 1Hz Chrono Pro timing to average them out).
The difference is the CSC5 grips from cold and gives consistent grip for the duration of 7-10lap stint. BUT here is the rub, the outer edges wear out after maximum of 600 track miles (2 days), despite over -2.5 deg static camber front and rear. Pressures are 34-36psi hot. In summary despite the grip the sidewalls are just too soft imo.
The NS2R 180 needs at least 1 lap to switch on, then is consistent for 6ish laps after which it starts to squeal and slip, but after 3 days an 900miles it looks like it will last another 3 at least all things being equal, overall we were a little disapointed in the lack of additional grip over the CSC5 but happy with the additional endurance. We do run 34-36psi hot as well, so we may not have got our pressures right according to the other feedback. Will have to try lower pressures to compare.
The car is a stripped and caged e36 at around 1250-1300 wet with a tank full - two bodies of 80ish each on top. Running square setup 225/235 profiles. When we run a staggered setup we found that we could push allot when pressing on no matter the tyres with our setup.
We also run NS2R front axle and CSC5 rear axle square for a couple of days without noticeably loosing balance.
