So it's been a while since I've posted an update. That's because I've been so flat out! What a hectic month!

I'll go through the lead up first and then talk about WTAC and how massive the weekend was and how my mates/team helped me achieve a great result!

So PI as you may have read in Kory's write up didn't go to plan.

A faulty injector plug on cylinder 5 caused this...

The day after we had it pulled down and everything ready to go on Campbell's motor that he donated so I could get to WTAC.

We also noticed that the ASI ebay radiator wasn't handling the pressures of racing. Kinda a bit bent...

So we got a racepace spec radiator and so far it's great. temps have never been so low. It's crazy effective.

The lexan glass is now in.

Johnny and matt ripped into the doors and all up took out 15kg, that's just steel! Glass on top of that!

All this weight reduction got the car down to 1249kg with no driver and no fuel. Not bad for a full caged car!

So the mad engineers bent me up a Gurney flap for the rear wing.

Matt separating the fibreglass headlight from the mould. This by the way was tuesday night around 11pm. We left for WTAC on wednesday morning 5:30!

Front splitter painted last minute for WTAC

I think I'll leave it there for now. The WTAC story is a big one so I'll post that up at a later date.

That ASI radiator photo is exactly what flea-bay lovers need to see.

Good for a street car, not suitable for trackwork, reflected in the price.

I agree 90%

For most guys they are fine

But on a car like Russ'

Well the pictures speak 1000 words

Back on topic, how did you find the gurney flap Russ? Noticeable difference?

Love the build, though I'd be remaking the gurney lap if I were you. The height of the flap looks too large for the chord length of that wing. You'll be getting an inefficient level of drag associated with the extra down force the flap is creating. You should be looking at a gurney flap of around 5 -10mm in height.

Rad was fine for 1 year of track work. Got gradually worse. Seen them on other track cars so thought they'd hold up. No problems with cooling though, just construction. Looks like its deformed from high pressure. No head gasket issues, that's what we first thought haha.

Gurney flap and change of angle was very noticeable at turn 1 EC. The car felt way more stable and I think it may have had something to do with the final session being 1 sec quicker! The boot required re-packing after every session. By the end of saturday we had about 4-5 washers spacing it up! Need to do something more permanent now. Proper boot lid re-enforcement.

The gurney was actually mounted underneath the wing to begin with but spoke to an aero guy at WTAC and he recommended putting it above the wing so it sits higher as a result.

    • KW only offers a set for the R32 GTR. Popular options are D2 racing, Ksport or Öhlins. I have a D2 Racing coilover set, though I don't know for sure which one.
    • Well, the good news is you have more than one very good option for new coilovers in and around your country. Worth the drive over to KW to talk about GTR stuff.
    • Fair enough, I am in no way a tire expert so I'm not familiar with all the terms and conditions. I'll definitely note down the AD09 to potentially try in the future. Rain is not too big of a concern for now as I will probably only drive in the rain when I have to. And considering I still lack experience driving the GTR I'd more than likely take it easy too. I have coilovers in the car but as I barely got to drive so far I never bothered to even check if they are adjustable haha. The suspension is almost entirely old and worn as well so I suppose when I eventually fix that in the future that would make a huge difference.
    • There's not a great deal to report here .... except ...... FOR .... LSD!!!  I bought a Quaife LSD from the UK and shipped it here .... Wish I'd just bought locally cause the shipping and duty was $700! But there were so many diffs used in the E90s I just wanted to be absolutely certain I was getting the right one so I spoke with a supplier in the UK who builds race cars and they have heaps of experience with the E90s.  I pulled the diff out which was seriously awesome - I've never done anything like that before, I must have watched 1000 videos on YT about it as well as consulting the Bentley manual. It was super easy in the end. The diff was delivered to the awesome folks at Hornsby Diffs and will be back in a few weeks. I also replaced the diff bushings with some Nolathane ones.  Really looking forward to getting it back and getting back to the track or even the skidpan.
    • yeah... the 13kg/mm springs weren't always in there, I had 10kg/mm but doing a few SMSP commanded heavier front springs. It's so good now going into T1 and T2, just need more seat time and real tyres.
