Great report; it was clear that you are enthused again with the detail and emotive nature of the way you've written it! I enjoyed reading about the mobility and turn in following your changes, and it was interesting to see how Malc and you download to one another and make real changes to your laptimes :thumbs:
Where else can you get 1.6 seconds off an already fast laptime with no risk to reliability for the same kind of money? Driver tuition and support really is the way forwards when you get this serious.

Sounds great fun it was a bloody fast car before so now it sounds like it properly sorted should be awesome......

Just a quicky, good to see Christian and the Monster again and especially good to see the 2:08s pop up on the data, 2 laps, both in the 2:08s out of a 2 flying lap run. Real shame the conditions changed as i'm sure with a bit more running we'd have seen lower times.

As ever with setup, you gain some and you lose some, the key is to get more gains than loses. It was clear last time that we weren't using the whole of the front tyre and you could see that in some of the external photos from the day. Adding more camber was one option but would have had some fairly significant negative effects and requiring more hardware. Springs were the way to go and I remember from many <cough> many years ago we went for 1,000lb springs on a race R32, which seemed extreme at the time but transformed the car.

!! I actually found some footage of the car I was involved with, never raced it unfortunately but here it is (the yellow one) driven by Rob Squires!! well worth watching see how little roll they had.

A certain Mr Matt Neal who raced the other GTR R32 gives a commentary.

Going to compare the new data with previous data and see where the gains were and if there are any loses in terms of time.

Thanks all, but yes I am very enthused again, great to be back on track (it was June the old brakes let go) and be seeing real, quantifiable benefits from mods and money spent.

I can't say how much I enjoy Malcs analysis of the logged data and am definately going to go for the kit, probably next year. But it's his input that really helps and brings the numbers alive.

Interestingly he emailed me today and my suspicions were right, I was losing time under brakes but making it up in corner and exit speeds. Also increased lat G's from 1.1 to 1.33 so that's also good.

In fact I'm enjoying it so much I'm going to think seriously about going racing next year, work commitments and house jobs dependent.

Malc, post a link to the GTR you mention above please.

I'm genuinely chuffed to nuts for you chief and without wishing to jinx you or the car, it sounds like things are starting to click and fall into place

and to be able to actually see your hard graft, investment and determination reflected in your tumbling lap times is really good news bud

You can see in the video how stiffly sprung the GTRs were, more so than the Cossies etc.

Wooooah! What a cool vid, shared straight to FB!! Those group N cars seem so stock, amazing to think of a proper race car running full interior and only a half cage!!

Also amazed that was running 1000lb springs, looked quite soft to me..

Nice post

Yeah they are much stiffer than the cossie's and M3s. Much heavier engine i would guess too

Cheers Pez. I agree, although considering I've known you for about 4 years its about bloody time too, often felt like this :beatdeadhorse5:
