[ARCHIVED CONTENT] Consultation paper


"Wet grip limits
The proposed standards for wet grip are intended to ensure that safety levels are maintained as tyre designs change to comply with stricter noise and rolling resistance requirements.
The Commission has incorporated the wet grip requirements and limit values laid down by UN-ECE Regulation 117 into this proposal, with implementation dates covering new type-approvals from 29 October 2012 and all tyres fitted to new vehicles, and replacement tyres, from 29 October 2014. These requirements apply to Class C1 tyres only.
Whilst this requirement is uncontentious, some Member States and MEPs believe that the wet grip limits could be more stringent.
The additional cost to manufacture these tyres is likely to be only the cost to carry out an approval test that will add about 1p to the cost of a tyre."

UN-ECE Regulation 117

Annex 5 - test procedure for measuring wet grip.

 
As I understand it, the process will be that it will be illegal to "sell" any outlawed tyres from November 2012, then a period of grace will be allowed until they become illegal to "use" this will purge any left in the system, so in reallity we will have a couple of years to go, I still don't really get "why" though. If we were to look at the amount of accidents caused per year due to track day tyres I am sure it pails into insignificance against the amount caused by pissed up teenagers driving nicked cars.
 
Trouble is, the pissed up teenager in the knicked car has no money or job so is given a stiff telling off and let go. If he does it too many times they even tell his mum. The respectable performance car driver with track tires has a disposable income and can therefore by fined as much as they can get away with and will generally pay without being chased. Easy money!
 
Two points:

My track day tyres are better in most damp conditions than my road tyres (but not deep water I imagine). Proved at Donington - it was wet so my lad (David) came in and I changed it over to our road tyres. He went out and the car was worse.

Second - look around car parks and see how many people drive on almost bald tyres - women too with cars full of kids. It shocks me to think that they are on the road oblivious to it all and blame accidents on conditions.
 
Back to my mods. The pacelforce man came knocking again today. £170.36 to the seller and £23.05 to parcelforce.

Two wrongs dont make a right?:rolleyes:...I cant see this being a good defence if you get pulled over for using trackday tyres on normal roads once law changes.

And in response to the supply Vs demand situation, one of my mates supplies tyres for performance cars and he told me that its getting increasingly difficult to get R888 / 048's etc . Once the law kicks in, I cant see availability beyond 12 months, especially in popular sizes.

Todays goods instalment ^^ looks awesome. Those parts are certainly going to see the toyzed get faster, quicker if you know what I mean:thumbs:

Thanks, I really didn't expect them to not only look good but be really well made. For a budget ebay item I'm well impressed. Yet to see how they fit though. The downpipe will have to be cut about (the same as I modded the current one) but hopefully the dump pipe will fit OK.

Not really got a ring to it. Any other suggestions?

Yep, let us know how you get on with removing the old O.E parts
I want to know how easy them ol lower rear arms/pins remove from the struts ?

Looked at mine today and it looks like the main pin? could be stuck fast :unsure:
 
I was talking about the turbo dump pipe when I mentioned fit as I know there could be problems and I'm sure it will need modding in some way.

With regard to the suspension bits, I'm confident they will be OK. I've removed the rear arm pins several times and never had a problem. Just need to be cairfull with the threads, although I wont be using the pins again so I could just use a round drift and a big lump hammer. The new arms don't use the old pins or a cotter pins so are easy to strip in future.
 
Spent the day at Terry's playing with the Z. Stripped off all the old suspension, brakes, diff, and driveshafts. Fitted the 2 front camber plates and started cutting the towers for the rears. Forgot to get new flywheel bolts so couldn't get on with this today. They will be in tomorrow so hopeing to do the clutch/flywheel after I get all the new suspension and brakes fitted. Could be a long day.
 
GAZ only took a couple of weeks to do the sruts. I gave them the ground control top mounts which they modified to fit the dampers. The parts going on tomorrow are: Ground control camber plates, GAZ struts, Techno toys adjustable front and rear arms, Techno toys adjustable tie rods, Willwood AZ front disks and calipers, Dave Jarmen rear disk brakes, new bearings all round, and uprated front diff mount.

I also need to repair the front crossmember and swap the flywheel/clutch if I get a chance.
