BTW, i just ordered some rear pads and if you ever consider going RC5+ on the rear, forget about it. They're ridiculously expensive! Over 300€

I got the lines and fluid changed last week. It will be a while before I'll have a chance to try it out. The stock discs are probable the weak link now.

When the stock rear pads are worn down, I will get Ferrodo DS2500. They are about 160€ and I think they should match up the RC5+ pretty well. What did you end up getting?

I kinda needed these in a hurry so instead of rushing any decision(since RC5+ were out of question), i went for what i know to work and ordered a new set of OEM pads. I plan on making some changes (pads, discs...AP Sprint) in the near future so this will do for the meantime

Yes, that was an easy solution.

I had my wheels off today to inspect the work they did with the brake lines. All looks good. I also checked the brake pads.

With around 65 laps on Zolder and Nurburgring GP circuit I am down 1.8 mm from 17 to 15.2 in the front on the RC5+ - @brzest , you asked about that earlier.

I also checked the rear and they are down to 12.2 mm. I think new stock ones are 16 mm? So I probably have to change them soon.

Since I don't have to take the wheels off every other day as in the last months, I mounted them back on with my black Muteki SR35 lug nuts. Those lug nuts has symbolic meaning as it's quite a milestone - I didn't want to put them on until I was done! So this finishes my first list of mods, and the car is now the way I want it.

From here on it's driving and maintenance. And clearing out what issues may arise (brakes as an example, if I have to resort to AP Sprint too). Also I want to change the oil cooler and find a better solution to the sandwich plate. But it's all small stuff. Down the line, I would like the HKS Supercharger (that's why I won't waste money on engine or exhaust), but that's phase 2 for me.

What I need right now are new tires!! AD08R are up next!

This is what she looks like now.

Looks brilliant!

I am not sure if I really should follow your build, or if I get too sad not having my Baby around.

Thanks Michael! I can well understand your pain!

Then it's almost cruel of me to post this video (I'm sure you recognise all the roads).

The car is really transformed. I'm so happy with all the modifications (and I don't miss sliding, I want AD08Rs ).

[Tor]

It's 6 in the morning and I just pulled the trigger on 4x Yokohama AD08R in 225/40R18 for my 18x8" OZ Ultraleggeras. This is what happens when a thunderstorm is ruining my sleep.

I would rather have had dedicated 17" track wheels with 235x45 Federals, but I can't find any rims for a sensible price that I like. So the Yoks will be the solution for now. Daily drivable as well and probably as good, if not better, on track than the Federals. If I have to drive the car in torrential rain I can always switch to my stock rims with the grippy Michelin Primacys

I booked a track day at Zolder next month. This time emphasis on "day": 3x 1 hours sessions with 1 hour break in between, so I will there from the beginning to the end. So far I only drove Zolder and Nürburgring GP circuit, but it's enough for me to say that I definitely like a slower/narrower track more. Zolder is just perfect for our cars in my opinion, with a nice combination of the 2 chichanes, a tight 90 deg, some 3rd gear, and 2 flat out curves and a bit of straight lines in between with top speed 170-180ish KPH (110 MPH). It's so much fun!

And now I should have everything sorted. Oil cooler, brakes and tires - V check!

[Twinguin]

My first thought was: when I'm awake at 6am, I'd just hop into the car and enjoy the empty roads. But then I saw the weather pictures of Germany - you're right, better to stay at home then.

BTW: great vid. I like your left-foot braking. :-)


Enjoy your track day!

[Tor]

Thanks, I am very much a beginner with my feet and there is a lot of practice to do. But once the basics is there the practice is a lot of fun.


I got asked about the brake wear by PM, and if the Porsche cooling made a difference in wear between the inside and outside pad. I actually took a lot of pictures when checking them last week. Feel free to write here or via PM as you please if you have more questions. I just thought when uploading pictures I might as well share it here for others to see too.

For now there is no difference to be seen between inside and outside.




Those are the left hand pads and are both worn the same: from 17 to 15.2 mm with 65 track laps, almost exclusively on Zolder, which is very hard on the brakes.

These are sintered metal brake pads and appear to hold up very well:


If the wear difference would be the same with organic pads I don't know. I am very happy with these CL RC5+ pads! I have no issues driving them cold on the streets either. When used properly (occasional heating up) and building up a transfer layer on the disc they are very quiet too. After some days driving casually and especially after washing the wheels with brake dust remover (which will invariably end up on the brakes discs too) they start to squeal when braking slowly. It goes away again after some hard braking, and the wheels are dirty again.

This is what the rotors looks like just after washing the car and cleaning the rims. When there is more transfer layer, they have a more mat greyish surface. The rotors look like they took quite some abuse and depending on how the brakes hold up next track day, I might replace them with something better soon (DBA or Tarox) or at least when they are due for a change.


And finally the rear of the pads. I was very generous with ceramic brake paste when I installed them. You can't recognise that the are CL pads anymore, as far as I recall the backing plate was orange. It certainly got hot down there.

Hey mate, thanks for posting these, it was/is a very nice read.

Your whole mentality about the car is very close to mine.
I just bought the car a month ago and I'm still undecided which way I actually want to go (NA or FI) I'm similarly disinclined to spend on useless stuff. Altho my ruling isn't *that* strong as yours, something like spending thousands to make the car sound different is completely unfathomable to me.

My main motto is "to have fun with the car" - which means track days. I haven't yet been to one.

Anyway, good read, keep up the journal, please.

[Tor]

Thanks @ysu! This is the list of things I would do if going NA:
- Header
- Overpipe
- Lightened Flywheel
- Short final drive
- Intake blocks
- Engine tune

A supercharger on the other hand makes plenty of power on the stock exhaust for my taste (280-300hp) and because of the more power, the flywheel and final drive become less important.

I don't want to spend a lot of money on sound either, except when the stock exhaust is due for a change anyway (and I would still want it fairly quiet). It's pretty low quality (rust), so it won't take that many years.

In the end it's all a matter of costs too and how much money is sensible putting into a car in this price range, which each has to decide for themselves.

Another thing is that the list never stops. Going FI will likely present heat issues. So that e.g. means louvered hood and perhaps larger radiator. And what about that big brake kit? And and and...

[ysu]

Hehe. I already know that feeling of "and...and...and..."
Good stuff

[Tor]

Yes, it's either hit the brake and stop or keep going.


I got my 225/40R18 Yokohama AD08R installed today. They look brutal with the square shoulder and the thread is as advertised a lot wider than a normal 225 tire. Now I am actually happy that my 18x8 OZ Ultraleggera are the weird Toyota-Europe special ET43 offset instead of the common ET35. It looks great and very racecar-like.

They made a mess with when mounting them with that lubrication they use, probably because I told them please to be careful with the rims (the ET43 has been discontinued and are near impossible to dig up as singles). So I took the car for a thorough 3 hour washing...



...and then a 2 hour drive. Even with only a few miles, they feel like they have the double grip of the Pirelli Zero Nero GT and 10x more than the Michelin Primacy. I can only assume they don't need much breaking in?

I launched from 4000 rpm and the rears made like a half a second "squek" and that was it. Reaching the limit of grip going around corners is near impossible to do in a responsible and safe way. In longer curves the speed required is too high for me to feel comfortable. I did get the rear to step out slightly once in a tight curve, but with a hands-width of counter steer it ended by itself as the wheels gripped again - kind of like driving with ESP sport, only it was indeed with 5 seconds OFF.

The rims and the lower half of the car is ready to be washed again, as it is noticeably covered in brake dust front to back, so as you can imagine it's not because I was holding back.

So the last bit of "fun" is now definitely and complete killed.

Well at least the typical GT86 kind of fun. But seriously, my initial thought is that I wouldn't recommend these tires (or similar category) for a car that is only driven on the street. The level of the Pirelli was absolutely sufficient. I am curious how they will feel in the wet and look forward to track them.

I didn't dispose of the Pirelli, so when the Yokohama are done I think I will have them reinstalled and invest in dedicated track wheels.

Or maybe I will change my opinion after driving them for a while.

3 new videos from the last track day.

4 laps fighting a Porsche Cayman. That was a lot of fun!!

I've gotten used to the Yokohama AD08R and they performed very well on track. I started to like them on the street too. I set my rear dampers harder and the front softer and it's all more to my liking now (with the Pirelli I had the dampers the other way around).
