Anyone done a back 2 back Cups vs 888's...?

As the 888's are available on 19" now, and better priced than a set of cups..
Are they about the same on a dry lap..?
I nearly finished my Cups @ Silverstone yesterday..!..biggrin

not worth the saving as 888 overheat too fast

best stick to 19 inch Cups or swap to 18 inch rims and buy some Dunlops

(your CS looked great yesterday at Silly)

Cheers Shim... come say hello next time..! I didnt see any other CS/CSL's on the day..
There was a red / silver M3..

Sooo want to get out the same time as CSL and see where mine is now..! or if i just plain run out of talent..!

The slow traffic in GP1 made it hard work to get in the zone, and hook it all together, my brother was going to have an introduction to the tarmac, but elected to stay in the left hand seat..! back to GP2 next time..!

Back to tyres.. so the general opinion is 888's are not a match for cups over 6-8 laps..? typically a sessions worth..? is this your exp or grapevine info..?

I done a set of cups in one day at Anglesey the weekend frown Didnt really rate them TBH, compared to the Pirelli Corsas on my Strad or the slicks on my M3 racecar......

Just said on the other thread about suspension and tyres, however seem Hazy's post and there is the first one!

I have heard a while ago that R888 didn't like cars as heavy as the M3 (although maybe the CSL gets away with it) and Exiges or lightest FWD cars are better suited. That said, I know people using them on 996/997 GT3RS/GT2 and rating them highly.

Although they are expensive, no one has ever said anything bad about proper cups. If you can afford them, stick with them...

cups are the best road legal tyres on track on he dry, but as always driving style, car weight, drive time, budget weather all come into play and most tyres have their place.

but if you want grip and can set your car up right Cups are the boys

talent increase is the only real way of getting over the weight issue. Just get yerself a CSL and enjoy

Gp 2 was buzzing with the PureGT guys pushing 2,10 laps and playing silly beggars!

like for like cars/drivers i reckon Cups are 0.5-1.0 secs quicker than 888 and after 10 mins on track that will qickly row as the 888 go off. GP2 guys had problems with 888 on RSR at Silly this week as they were going off well before the session end and Cups were fine through the whole session,

through ewxperience of 888 they dont cope well with weight and therefore heat for medium to long periods. Work well on Lotus/Caterhams but always seem to suffer a little on Porsche/BMW. If you dont run too many hot laps back to back then you may be fine but rubber compound is not up to cups (until it rains)

Rather worrying feed back!
I've just purchased a set of R888's for my M3 CS, around 100 miles in they seem great.
Nurburgring trip coming up at the end of May so we'll see then. Will be well p@ssed off if they over heat before the end of the lap.

Has anyone actually ran them on their E46? The Porshe's seem to work well on them?

unless you are Walter Rohl lurking on pistonheads, I don't reckon you will have a problem overheating your toyos at the ring - it would only be an issue if you are really on it. On a shorter twisty circuit you would have a chance of overheating them but no worries at the ring.

I will be interested to hear your feedback on these, but i am sure you will be fine on the ring, its not super twisty and heavy on the brakes.. I did talk to a guy running 888's on an E46M3 on 18" on stock Geo at Sillystone last Monday, he did all day on them OK,.. I went to see his car at the end of the day to see how much tread he had left to get home on.. he stayed out for a full 30 minute session as i did.. they were fine, for road work they will also be better if it rains for sure..!

I didn't get the chance to follow him for a few laps to see if the grip was about the same tho...

Good feed back chaps, cheers!

Certainly not as on it as the serious boys over there so should be fine. Did a 8.22 BTG with the CS in stock format last year which included rubbish Sport Contact rubber.
This year i've AP's, suspension and R888's on CSL rims.....can't wait to feel the difference!

Anyone else planning a trip around the 28th May?

Keep meaning to get involved with more trackdays down south.....perhaps later in the year.
Up in SCotland we have Knockhill, Knockhill or Knockhill!

Thats why my Caterham's my first priority....lots of Hills & Sprints up with us!

I'll be sure to let you know how i get on at the ring with teh Toyo's......hoping to get a sneaky video again this year.

If anyone would like to chip in for a set of Cup's for my M3, I would be happy to do some back to back testing when I am over at the ring with Craig at the end of May yes

Thats us back from the Ring in 1 bit which is always a good thing!

Had a great time, far too much traffic though! AliM and myself were in our E46 M3's with R888's and they are brilliant! 19 laps and the drive there and back and they still have loads left in them. Wearing perfectly flat aswell. Ali managed a 8.07 & I posted an 8.11 in rather heavy traffic aswell so it goes to show the Toyo's must have been working!

Much cheaper than the Cups aswell. Think i can speak for Ali on recommending these tires after a hardcore road or track tyre.

Interesting feeback Craig.. and some good progress for you this time round.. how much of the gain would you attribute to the brakes/suspension/driver improvment.. and then the tyres..?

Craig and I are both running ~ 2.5 degrees neg camber on OE top mounts and with the drive there and back + ring time, the tyres have worn evenly inside + outside.

I did three laps back to back on the Sat and the tyres did not overheat and maintained grip throughout. I have run R888's on quite a few cars and they seem to work best on the M3. I ran them on a Clio 182 last year at the ring and I did not seem to get the best of them as I was not running neg camber as it was non adjustable on OE shocks.

I reckon the R888's give you 10 secs over road tyres such as PS2's and would definately say my car has a 7 min lap in it on those tyres.

Craig - When you phoned to say you did the 8.11, I asked about traffic and you said it was pretty much a clear lap... now you are saying you had traffic!?

Definately, although I would still be interested to try Cups next to see the difference!

Jack up the front of the car so that both wheels are at full droop. (Both wheels must be off the ground or the anti-roll bar will stop you dropping the strut)

Take off your OE strutbrace. (Four 13mm nuts)

One side at a time, undo the 3 x 13mm nuts on the strut top holding the shock. Before completely undoing them, put a jack under the wheel/tyre to stop it from dropping completely. Then you can completely undo the 3 x 13mm nuts and lower down the strut.

You should then see a little pin in between where the 3 nuts go on the actual strut top (just on top of spring). This pin stops you from using the full adjustment on offer by holding the strut top in its OE location.

Remove it.

You can then jack up the wheel so that the strut is once again in the proper location, release some slight pressure on jack and push the whole strut all the way in to the centre of the car so that you are making full use of the elongated holes in the strut top (shell of the car).

Once this is all the way hard in to the centre, jack up a little to hold it there before re tighening the 3 x 13mm nuts.

Repeat for the other side.

Refit strutbrace and stand back and see how much it has moved.

Made a massive difference on mine.
