Feed back please on Mich Pilot Sort Cups.

[Eduardo de Sousa]

Hi to all,

I am 90% close to remove my Viper from sale and looking to do some mods to enjoy the car.

Could you please tell me if some of you changed to the Pilot Sport cups on the SRT10's on 295/30/18 and 345/30/19 and felt the same problem than the run flats with following all cambers and imperfections of the roads?

I know the PS2's cure the problem but worried of ordering Sports Cups and back to zero.

Thanks,

Eduardo.

cambers and imperfections of the roads?

you should have got rid of the run flats a long time age ... every day counts!

Every other tire is much better and you will have to decide whether you want an aggressive track set up (alignment)
or for road use...track set up means that the car will be almost not drivable on bad roads! Will follow the grooves badly!

I always wondered why you want to sell that car because of an oil pan and new tires (you will need anyway).

I have the cups but havent run on them yet

Mixed feelings really,

Just spent £39500 on a sport car, got an awfull ride back from London to North west with car going everywhere.
Then found out i had to spend on top £1500 on tyres + £1500 on oil pan and other things to get it right. And was advised as well KW variant two shocks at 3000 dollars, braided brake lines.

Just thought , i wasn't doing it again and would just get a track car. That's why.

Now i just calmed down a bit and will do it step by step (again, like my preped Mustang)

Eduardo.

PS ( would the Dodge road alignment be ok, what would be a mixed set up please.)

thanks.

Ok, Thanks.

You may have a lot of fun at the track with good tires and the right setup (even road setup) also...may be not the fastest laps but without a roll cage etc a good idea anyway

Of course, two sets of tires may be an option too. One for the road and one for the track!

I remember an (old) joke friends tell me over and over again...

Ferrari owner trailers the Ferrari to the track on a trailer.

First thing after unloading the "race car" is draining the engine oil from the dd pulling the trailer.

Filing the drained oil in the Ferrari to go for the races.

After the race day, draining the Ferrari and putting the oil back into the dd.

That's how you can save some serious money!

Will probably keep road set ut then. Regarding tyres looking more for a Mix (track and road) so Sport Cups could be ideal if ride ok on road.

Will wait for some more feed back on tyres.

Thanks.

I will swap over after this weekend and let you know what I think of the cups

Fantastic !!!!!!!!

Fingers cross they don't run like the run flats on bad roads

Thanks,

Eduardo.

I never had any problems with the run flats either on the road or the track...but they are not as good as plain tyres you car should track fine on the road, so perhaps another problem like alignment ??

The sump mod is a luxury that you could do without but all cars do suffer from oil surge on bends and having most of the oil half way up the engine is not recomended, however I also tracked my SRT with no problems, had it for over 4 years and did lots of track work, ask any people on here, but the G force is increased with sticky tires, most Vipers that had track engine re in the US on banked tracks with very high speed turns and on slicks.

I kept my run flats for over 2 years and only really replaced them due to wear and to stop excesive wheel hop which can kill your diff.

[ViperGTS99]

In over 10 years of driving Vipers I had different tires, setups and air pressures in the tires...

With an aggressive setup (alignment) the car will follow the road imperfections like hell and the tires have only 50% contact to the road going straight...I have to look for the picture where I did a burnout to see the width of the contact patch with the road surface

Tire pressure. I use 1.9 bar which is about 27-28 psi - is perfect for me.

Tires. The PS2 are far superior to any other previous Michelin ROAD tire.
The cups might be difficult if the road is wet or damp but much better on the race track.

Check & adjust alignment AND tire pressure and you will have a totally different car with the right tires!

Looking to do Spa in June, so quite long bends. Might help.

Will have alignement checked too. Thanks.

From memory the problem is L/H turns and SPA is mainly long rights from memory.

Just to add my tuppence worth. When I bought my GTS I had a very similar experience, the car was a danger to myself and everyone else. I tried a few things, alignment, tyre pressures etc to resolve it but the problem only finally disappeared when I changed the tyres to PS2's. The problem had been the very old tyres on the front of the car. My GTS now drives brilliantly. The PS2's are very grippy, so much so that I seem to recall Fishboy burning his clutch out because the rear tyre grip was better than his clutch (he was doing burnouts though...).

Anyway, at the moment event tyres are selling ps2 345/19s for £300 a pop. I bought my last set from there and am very happy with them. If you can try to make sure you get the newest age ones (each tyre has a manufacture DOT code on it) that you can to extend the amount of stickiness they will have.
