The Kuhmo cup lap record is a 1m15.870, I appreciate that they aren't on slicks but they are race cars with no carpets!!

well I was just presuming you were Jason PLato...

However Sy on her did I think 1m 18s in a CSL with Intrax and Cups so I thought with Spires geo on Nitrons and Slicks you have to be 1,5 - 2,5s faster

Took the track bitch to Snetterton Monday, running -5 neg camber up front, square set up 18 inch on 24/64/18 slicks, bad boy rear wing, stripped, intrax, ap's, full heavy weight M3 OEM exhaust system, corner weighted, 1400KG with full tank of fuel and I reckon it would give a CSL on 18 inch Cups, square set up, Intrax, AP's a run for its money.

I didn't think it could be done but with all Adem's help its nearly there.

Just need a dry day to test it out properly.

Best on damp to dry conditions on speedo round coram was 105mph entry and 95mph before braking. Quicker than CSL and more sturdy, but was on slicks. Must be the rear wing.

I think in the dry I could take bomb whole flat out, or slight lift.

But also done 13+ more track days in the M3's favour.

Saying that, Adem let me take his CSL out on fresh cups, after he spent the morning scrubbing them in and grip levels were the same.

But being able to push harder and know a 2nd hand engine is £1500, front bumper = £250 means that you can just push.

Realistically its all down to the drivers ability and how confident there are with the car moving around near the limit.

Cannot wait till the next Snetterton date.

You are absolutely right, pushing on in a track slag gives you a lot more confidence than wringing the neck out of a £30K + CSL. Thats got to be worth 3 seconds a lap easy!

With -5 on the front I assume you only use those settings with slicks and set back to -3 for cups / semi slicks?

Struggling to get the slicks working across the full width to be fair as I am running at -3 degrees camber front and this means the outside 1/3 of the front tyre isn't being optimised. But don't want to go any further neg camber as it'll eat road tyres!! To be honest I don't think I am much quicker on the slicks than the Nankang NS-2R's (surprisingly good tyre for the money tbh!!), will try some cup 2's after the Nankangs if they are available in 265/35 18 by then!!

Nah, sacked the cups off. Sold one set of CSL rims and the other set are on the csl.

I drove to track like that on 19inch square set up with goodyears on.

Snetterton and bedford are only 40min away. If on a longer journey I would use the 18inch rims and put back to -3.

On cups -3.20 worked best for me with -2.20 at the rear with even wear.

Ive tried -3.20, -4, -5 on slicks and -5 works best for me.

On -5 all the width of the slicks got used, had to abort a couple of laps when it started raining on slicks as lost the front end round Riches (first corner on pit straight).

Wouldn't mind a 4.1 diff but happy as the car is for now.

I cant see why an M3 prepped for track shouldn't be same speed as CSL both on cups tbh., Weight may be lower in CSL and it will have say 20-25bhp more but you will be around 50kg lower than most CSLs and in car as you say, you can take liberties.

A better diff and slicks have got to improve it above a CSL surely.

come on then!

so going by what youve said, you looked quick at BEdford nut if slicks not batter than cups id say you should be at 1m19

billyboysm3 · 03-10-2014, 08:17 AM

Slicks are much better than cups unless you get a shagged set.

You and Sy done a 1.18 in Csl, intrax and cups.

Will do Donny after snetterton and Bedford gt.

Sy was in 1m17s and Barry did mid 1m18, i think mine was 1m19 dead

im going back as well

a wing and down force will make a difference i think on the time tween redgate and mcleans in particular

billyboysm3 · 03-10-2014, 12:29 PM

Rear wing is where its at. Adem's making something special up for the front.

Sy, just seen a picture of your car on Cutters, looks awesome.
