Well the car performed amazingly on Saturday. Not sure why, I did barely any prep other than some fluids.
Mallory was incredibly wet, rained all day, but the Rainsports were excellent. I could perfectly balance it between under and oversteer and didn't spin out all day.
Short video of a very wet morning lap:

Longer video of chasing a Clio around, which was fun. I was faster in Gerrards, he was faster getting out of the hairpin.

Nice Job :-)
Always love your videos but it looked like that Clio was holding you up, what's your opinion would you prefer he moved over and let you past or do you like to have a little play?
Nick
He held me up at Gerrards but pulled away from me on the hairpin. I think I was catching him on a clear circuit so maybe move over but it was fun driving with a confident driver. I showed a headlight up the inside towards the hairpin on one lap and he immediately took the defensive line so I think he's a racer lol
Yours is faster through the bends no doubt! That steering wheel is too small; you shouldn't be taking hands off the wheel to counter steer - the diff & rack should mean you can get it back. You do still have to be fast though with a short wheelbase :D
Good Video Iain, Glad to see you found some love for it.
Did your car have red wheels on? Someone mentioned that it was me at Mallory (even though i don't have red wheels).
I had the bright orange ones on (my wets)
Did you get the new rear beam on, if so how was it ? And where is House ,doesn’t seem right not following a red Nova
New beam isn't on yet - I need to source some handbrake cable guides and devise a roll bar setup. I did have the new chassis brace and solid rack mounts to test out.
Housie couldn't be bothered to come up to see me. The main purpose of the day was testing my mates new MX5 coilovers!
If the beam's with the rose joints you wont need the ARB
Isn't the new beam going to be this one? (or like it?)

Fit it and find out ;O
That is the actual beam yes. My understanding is the link bars keep the geometry in check, but will not give the benefits of a roll bar reducing wheel-to-wheel roll.
It's obvious isn't it!!
The torsional stiffness of the additional bars secured to the beam using flexible rose joints add dynamic load spreading, meaning that the additional G-forces caused on conditional turn in translate through the flexible joint and into the centre of the beam, thereby fully dissipating any form of oversteer body roll or fluctuation. The only real way to work this out is to install a torsion/roll meter and assess if the car does indeed flex the tyres more, if it does then you'll know that the rear beam is indeed on solid mounts and the shocks are too stiff. The answer then would be to try 5 different sets of rear shocks and then after that install an absolute central roll limiter to prevent further discretional body roll around the Y axis.
However if you just wanna bolt on ARB's willy nilly then don't come crying to me when you're backwards in the gravel
Revel in the subversion.
All an arb does is (in part) add strength (you no longer need), unsprung weight (I expect you wouldn't like) & add effective spring rate (when it now can just be achieved through a change of springs should you even need it).
I'd prefer to limit roll with a roll bar rather than increase spring rate. It'll keep the rear end safer on the straights, and a roll bar is a lot more tunable at track side for wet days - none, standard, 22mm and 25mm are all available and changed with 4 bolts.
You'd be better off replacing the bushings for spherical bearings
Wow, great work. Read the whole of this thread from start over past week whilst travelling for work. Now motivated to get mine back on track as its not been touched in years... Thanks!
Nick are you the guy that bought Nigels yellow atb / carbed / alpha ign nova like in your avatar?
I've finished the toe-linked beam, fitted it and tested it. It was eventful, that's for sure.
So I needed a roll bar on the new beam, so I fabricated some mounts out of 25mm box section with captive nuts to facilitate the fitting of a mk2 Astra GTE secondary ARB:

Fits nice and snug:

is that a front or rear gte astra roll bar mate?
Took it to Donington yesterday for a test. First session went OK, the new beam was very oversteery but in a predictable sort of way. Second session it thew me off the track, made a horrible noise turning right and I went back to the pits to investigate.
https://www.youtube.com/watch?v=aXb5nX07SVY&feature=youtu.be
Upon further inspection the wheel had touched the tie link bolt and machined a big groove off it. Confused, I did some testing in the pits to try and replicate the issue before going on track and risking my life and a red flag only to get a right royal bollocking for doing "donuts" and almost sent home there and then. Apparently she "wasn't born yesterday it was obvious what I was doing". Riiiigggghhhtt.
Then we noticed the geo had changed to positive camber after my testing so it was loaded on the trailer and took home.
....to change the beam back to the original! Took me and Harvey about 30 mins with the use of a lot of cable ties.
Positive camber yo:

Hmmm, it actually looks like the new beam is missing the strengthening here!
http://iainel.co.uk/images/forums/NovaWIP2b/461.JPG
Oh yeah, that'll do it!
http://iainel.co.uk/images/forums/NovaWIP2b/462.JPG
With the old beam on, I towed it back to Donington and got a session in before 1pm lunch!
This was entirely my own fault, I didn't twig the plates were missing when fitting, despite the tell-tale signs. The previous owner had a grp-A 2 pot set-up which does not require these parts - d'oh!
Back at the circuit, I did a full afternoon session ignoring some severe wheel wobble due to the unbalanced wheels. I was actually using some well worn R888s instead of the usual Michelin slicks as a test.
http://iainel.co.uk/images/forums/NovaWIP2b/463.JPG
I actually really rated the R888s over the slicks. They gave much more feedback by squeeling when you pushed them too hard, wore much more evenly and over-all were much more enjoyable to drive. I'm going to move to semi slicks instead of slicks from now on, despite more than likely slower laps.
Here's a session towards the end of the day:
https://www.youtube.com/watch?v=2qqVi6nuijc
It's a mk2 Astra GTE 'secondary' rear ARB. Apparently they have two, one Nova-style one through the middle of the beam and this one attached externally. I believe it's the same as a mk3 Astra GSi and also Saab 900s and maybe 93s.
Thanks to our local lovable rally man Paul (rallymarshal) for the ARB xxx
cheers, car looks planted in the 2nd video.
What system is this please Iain ?
Cheers

Love the videos, was your rear wheels not spaced in more without that plate fitted?
Whats the round bit above the D shaped hole in the end....
