Have a look at where the marker is on the lap plot in post #14. Like I said it feels a little 'daunting' to drive, but I have some more mods planned this week which should see the car stable at 1.4G continuous through there, and hopefully another 10km/h faster :P

Here is the G-Circle for the car Fungoolie. As you can see it has some grip, but it could be better!

Ahhh, so cute, a heart shaped G plot graph :P))

Since you are getting up to 0.9G in left handers and 1.3ish G in right handers does that mean right handers are on camber, or it simple means that left handers are not suited for faster corner speeds??

You're reading it the wrong way. Acceleration and braking are along the Y axis and lateral acceleration is along the X axis.

Designed up and fabricated a front splitter for the GTR over the past few days. Making it rigid and them mounting it properly to take force across its section was a little harder than first thought, but we have a result that should provide a good aero balance at high speed now :D

Pics later :)

Willall Racing just ran a 1 min 12.19 at Mallala today in their JDM R35 GTR.

Faster than the group A R32 GTR!

Congratulations Keir & Martin. You guys are flying now.

E85 looks like the way to go, when are you going to fit the bigger turbos?

Wish I was there................. oh well. I will keep working.

but there is a massive diffrence to 40 laps at that pace and a one off

agreed - consistent times are much harder than 1 off times BUT i still want an r35 :)

1 day...it is coming

3 sec difference so there isnt much in it

New PB today testing the front Splitter and our new Braking System on the GTR

In 35 degree conditions and on a used tyre set we reset the 1:12.19 to 1:12.10.....very tight.

On a similar day to the first record we could expect to drop that time 0.5 or so. The Mallala 11s are in sight for us soon :down:

In much colder conditions (where we have found it is harder to gain outright tyre grip with the GTR tyre set we use) we upped the ante again today with a 1:11.68 at Mallala, a neat improvement, and with some direction now to start steering the car towards a 1:10 second lap :(

Yes, yes we did run a new tyre set, however we struggle with the GTR in the cold ambients (around 10C taking into account the wind factor today, and track temp under 21C most of the day). Grip is very hard to find in these conditions, we find the GTR likes 32 - 35C ambient with the 60C track temps that it delivers. Its extremely important to set the bump and rebound rates of the suspension correctly to get the tyre working on the track to suit the conditions....we are learning more about the R35 chassis every day :(

Its not surprising that your gtr is quicker in mid 30degree than a much cooler day...it was the same when I was racing bikes, higher temp gave more grip whereas a cooler day gave more power and grip is king on the circuit

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Yeah i found that alot of parts can be wrong or "very" hard to get the real right one. I already bought some brakes years ago on me "old" GT calipers and they were wrong too 😄  I told them too. Even send them pictures...but they said "EBC catalogue has them on my car... So i dont know what their answer will be. I call monday them and let them know that they are really not on my car. If they were they would be already on a car...

      What brakes on R34 GTT(Europe)

      Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.

      What brakes on R34 GTT(Europe)

      By Kapr · Posted

      Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?

      Lock up the old for sale / wtb threads.

      Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.

      R34 Gtt Wheel Offset Advice

      By Kinkstaah · Posted

      This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
