I’m not sure I would want 850kgs being powered by 350 horses on anything less then 1cs??
Where's your sense of adventure?? :lol:

It's just a thought, 2.75% is a lot of lap time when you've already got a serious handicap for the above. I'm just wondering if that would balance things up as my power to weight would be best suited to slicks and some aero to overcome the handicap?

I'm not bothered about being the fastest outright, I want to be competing for 25 points every round ideally..

Well James, my son tells me that most young upstarts who, through ignorance of style and pedigree, pedal the lesser, small sports cheese wedge variety of perambulator, are able to switch programs on the Electric Control Unit(over the shoulder safety driver unit) so they get a sort of Radio 4 engine effect rather than full on Sixmusic. I wonder if there's something missing, courage maybe, that causes excessive caution when wet.

I'm with you on the power/weight thingy, although I usually find 350 hp in a diesel shunter!

I've never experienced this excessive caution when wet thing and I'll join you in your raindance anytime :lol:

Ok, I thought the tyre situation was as easy as getting a set of super soft 205/50/15 V70A's; however I can't find anyone that sells them/has them in stock!?

There seems to be a few more choices now and looking to 1B's seems a good idea, I even thought about 1A with the 2.75% loading on the 1C's, but wasn't sure if you can run them in modified?
The Kumho's normally come into stock February/ March time Paul. We have ran them for years now. With your power super softs won't last based on our experience of soft's certainly on the circuits. You'll probably need mediums at the front at places like Ty Croes on a dry day. I would budget for 2 full sets of Kumho's for a season if you want to be competitive.

I'm with James you will need at least 1C's to put that power down; anything else and you'll just be throwing your power advantage/ handicap disadvantage away.

You will need to be the fastest outright (or very close too) otherwise you are not going to be competing for the 25.

Ah, OK I'll wait and see re the Kumho's.. I used super soft V70's on Tango and they were pretty much gone in less than a season, and like you say long circuits destroy them at an alarming rate! I've got some pretty much brand new medium Yoko 048R's on at the moment but they're nearly 5 years old and didn't feel too good on the test day, certainly not worth the 2.75% as they're 1C's..

Remember we're talking smooth linear power delivery not turbo power delivery, the only tyre issue on the test day was understeer, traction was excellent. I do think you're absolutely right, I'm just making sure I've explored all the options..

just looking at RS3 after discussions today and I find that they're not available in 13" to replace my 205/60/13 R888R.

but......195/50/15 are identical rolling radius and very reasonably priced.

I think I will be doing a direct comparison at the test day :D

Yes they’re silly cheap in 195/50/15.

Has the handicap put you off using the R888Rs ?

As with any reg change, it's made me seriously think about which would be best for my car.

I knew from the outset that with only 110 BHP I'm aiming at the hills rather than the circuits and a 2.5% penalty is a huge difference that I don't think I could make up - which is what I hope to conclusively prove at the test day (the only problem will be if it's wet that day!)

You’ll definitely be quicker on the RS3 if it’s wet.

Further to this discussion.

We discussed tyres at the driver meeting yesterday and the 2.5 penalty for B's. The consensus was that most CM entrants would be on A's because they tend to drive to events.

Well....of the 61 CM entrants in 2017:- 21 on A's, 33 on B's, 3 on C's and 4 on slicks.

I'll take a look and see if any high powered cars run on A's because I know that's the way Turbster intends to go.

Not sure what it proves but its interesting :oops:

There are many tyres that fall into the B category that could be used to commute to events. Yoko AD08R would probably fit the bill, but I doubt they’d be competitive against an R888 in SG compound on a hill climb. I think I’d want to trailer a car on the SGs though.

Just had a look at the high powered cars running 1A's.

The CM winner last year (TVR Griffith 500) was one of these who has a handicap factor of 94% (our car is 96% plus).

He scored 7 25's BUT only 1 was on sprints suggesting that A's provided a bigger advantage handicap wise on the hill's presumably because those on B's weren't able to get them up to temperature to achieve the time advantage :?:

I guess fast drivers and competitive cars will always do well on handicap whatever tyre they are on BUT I guess being on the correct tyre is the way to go if you want to win in what is a very competitive series.
