GR86 Some pics of my work in progress.

Great stance. How much have you spaced the stock wheels?

yes, I run 20mm spacers on the stock wheels.

 

[ninjin]

That’s surprising given the vast amount of clearance the AP CP9200 kit I have on has with both stock and wider, more dished aftermarket 8.5” wheels (all while keeping the stock dust shield too - the disk is not more inset than stock).

Is this the OEM Brembo kit or using Megane RS or something else entirely?

It's the wheel design that is the issue not the brake kit. The Stock wheels even clear the Brembos.....

I'm using Brembo's from Impreza, Disks and Calipers are a bolt on and don't require bridges for the calipers.

 

[ninjin]

had some time to play with my wheels today and see if I can find the solution. Bought some 3mm spacers and this is enough to clear the calipers... However, there is only like 0.5mm clearance. I would feel more comfortable with at least 1mm to cover for any expansion of the caliper on track days. In reality it shouldn't expand but 0.5mm is cutting it too fine.

So got in touch with the shop and asked them for 4mm and they said they only do a 5mm spacer when custom made, as I want it to be hubcentric with 56.1mm bore to fit onto the hub and 75mm on the hub ring to center the Enkei.

After worrying if a 17x9 ET38 (ET43-5mm spacer) would fit with 245/40 17 tyres, I went outside to see. With my current setup, the new Enkeis with spacers would poke out more 9mm. I think I got around 20mm to play up front with so thats good news. I may have to run more camber in the rear though but thats easily achievable as I have adjustable lower arms.

Looking around on the web, lots of Americans are running 17x9 ET 38 with 245/40 and have zero rubbing issues. So that has given me the confidence to go ahead with the 5mm spacers.

So the plan of work is 5mm spacers and extended wheel studs just to fit some track days wheels.... They do look good though!!!

here are the pics:

Eyeballing it, I got plenty to poke out 9mm more than currently.

This is what I will have made up in 1pc. Currently its just a hubring ontop on the spacer.

 

[GRistopher]

It's always the way

Not a wholly valid reference but here's a 245 on a 17x9 +45. They taper in on a 9 inch. At least these Goodyear do. I think you should have enough space especially with lower arms. Good luck, they look nice.

 

[ninjin]

I found these pics online with 17x9 ET38 245/40 tyres. Other than tyre brand, should be the same setup as mine and he has no rubbing.

Today's mods: CUSCO harness bar and Kansai Service Strut brace that clears the spare wheel. Both need trimming of the foam inserts to install but no carpet cutting. When the boot carpet is back in, you cant see anything.

When you want to run harnesses, you fold down the rear seat so the belts can clip into the bar.

Both need trimming of the foam inserts to install but no carpet cutting.

I didn't bother trimming the foam, there was just enough space to jam them in with a bit of a squeeze (Kansai Service Strut brace)

if you dont trim the foam, then you cant install the popper.... In hindsight, should of used your method!

Managed to do some work on the car these last couple of days. Fitted a Oil Pressure gauge and started the install (finally) on the Cobra Alarm.

So far installed the Oil Pressure gauge, straight forward. However, the cheap arse gauge I got isn't accurate. When warmed up shows 0psi pressure at idle

Going to try another gauge and sender. If the same, will bite the bullet and get a Defi or AEM. When above idle, it reads fine.

As to the alarm, mounted the siren and thats it! Tackle the actual wiring into the car's loom when I next get time.

 

[ninjin]

After 1year of having the Cobra 4615 sitting on the shelf, I got round to installing it.

Cobra don't have wiring for the GR86 but the BCM looks the same as the GT86 so they were confident.

Well, the wiring is different and it won't install following the GT86 wiring instructions.

Currently working with Cobra Tech dept to see if we can work it out.

 

[ninjin]

So... Beford Shake down done and I can say I'm happy with the results. Taken me 3 track days to get here but the smile on my face yesterday was definitely worth it.

The biggest improvement I found was the Anti Roll bars from Whiteline. Made the car much less rolly in the corners.

Next mod is definitely the bucket seat as I found myself trying to hold myself in and not being freely to concentrate on steering.

 

[Grblue86]

Remind me , which whiteline kit did you go for? I cannot find how much more stiffer they are than OEM and much less how each hole om the bar relates to the OEM bars.
I have ordered the Perrin 19mm front bar but is on back order, been asked if I want to cancel/wait/order something else. I went with the Perrin as there was some data behind it and I didn't want to go too stiff so really interested in knowing how the Whitelines compare, still plan to keep mine a weekend road car.
Was it a pain to fit them? seen a few videos where people remove the whole bar plus braces from the car.

 

[ninjin]

Its all about thickness if its a solid bar, So you can work out the % change. Also, there is no right or wrong for mods. It's all down to your preference, your driving style. Adjustable mods just give you the chance to fine tune the car to the circuit you are that day for maximum performance and minimum lap times.

As an example: when its wet you actually don't won't any roll bar, you want the car to lean because if you have too stiff roll bar, the car will just understeer due to lack of grip. Like I said, modding a car is a minefield. It's taken me 3 track sessions to get my car to where it is now.

I went with this, with front set to least stiff and the rear middle.

I've put mudflaps on mine

Just doing housekeeping on the car and looking at the wear and tear from the last trackday at Bedford.

With all the OPR removed can see heavy shoulder wear on the front tyre. This tells me that I don't have enough front camber, so time to add another -1 degree for the front and rear. There was no abnormal wear on the rear tyre at all.

 

[ninjin]

The car was braking really weakly during the day and even on road use, when up to temp they felt like mush. Pads are DBA extreme Performance and are meant to be fast road/track day. Although plenty of meat on them, the pads have overheated and hence the rubbish braking performance.

Running Endless MX72plus now and lets see how it goes. However, I think its time to get proper track pads next time.....

 

[ninjin]

and lastly.... Finally test fitted the new 17" wheels with 245/40 17" Nankang CRS and they fit! With the extra -1deg camber to come, they will easily clear the fender.
