GR Yaris Hello there

Fun times but sadly too little gravel driving. Need to do another visit later this year.

That's mad! I haven't taken mine off road yet... she's too clean! I can't do it.
Looks like fun though. Just gave you a follow on Insta, @Lensmanvideo - I'll flick you my video, when I get around to making it :)
 
With little elbow grease, hot air gun and saw its finally there. Happy with the result though it was maybe x2 more difficult than anticipated - gr and tight spaces..!

Noticed in street driving iat maybe tad higher (hot air being pushed towards airbox?) but on wot all normalizes.

Oil maybe 5-10’C cooler, no exact figures due to lack of logging of oil temps at the moment
 
Got the hrns cooling stuff - tried to install the rear diff cooler but didn't figure out where as there was no threads in the bottom part where it was supposed to go..
any ideas?

Oh yeah maybe those 'thread rivets' or what are they called is needed. new tools to the garage then..
 
Boosted the ceramic coating and added few extra ducts for driveline

Calculated now that I've got 7 additional air scoops for the car..
- two for brake discs (HRNS)
- one for oil heat exchanger (custom 130x130->63mm)
- one for airbox (forge)
- Driveline & Transmission (3pcs, HRNS)

That's just utter madness! Though like the approach that car can take whatever beating without any heat issues.
Well, not maybe 100% as it would require oil cooler but with these tires I don't see that necessary. With semi slicks and stiffer suspension - then yes.
 
Looks like Im quite sensible on the brakes 21tkm and few spirited drives. They say that braking kills the speed..
Must say I do not use that much brakes in road drives - mostly in hard use only in track and as with stock tires won't do many hot laps. usually 4-5 per visit.

Had a nice free evening yesterday to tease GRs great abilities on twisty roads. Also met fellow GR enthusiasts. Glad it will get soon dark again so we can use the light power from Led Bar.

Took the car to 20k service with driveline oils
- front diff oil was out of stock so replacement was postponed
- front brake saddle seals were shot -> was told it was my fault in replacing brake pads. I question this can seals be damaged with pad removal - GR yaris has really easy pad removal and assume seals should last pad removal. Discussing this still with the garage
- front left driveshaft had loosed its band from the tire side - shop claimed it was brake cooling ducts that had dismounted the band but find again this hard to believe. band should keep its place even there was a hose next to it.
- was told stock front pads were too worn i.e. harneded even though there was still 6mm left in the pad. Find this again hard to believe as pads work well when they're warm. So no braking issues. Think stock pads should last longer especially as there was still lots of surface in them. And haven't really driven car that hard on the track or on the road, just few spirited laps with little brake use (as the pads were not worn).

Will eventually upgrade to better pads but overall bit disappointed on the brake wear with the car, given I haven't really pushed it to the max. Hope the warranty will cover some of the issues but let's see.

Just to let you know that the ducts on the brakecooling will touch your driveshaft at certain angels of steering and actually wear on the rubber and the band. I found out the hard way.

The brakes are know for wearing out fast no matter how you drive, they have good bite and works well on a stock car but with wide tires they only last one or two trackdays. Its sadly a designflaw with thin discs and thin pads and there is no easy way around it sadly. Just keep an extra set of pads in the boot as switching them out is a 5min jobb.

Cheers thanks for input - i have feeling that right side does not interact with shaft but left does - need to think how to remove the issue.

I dont drive with semis but stock tires so brakes should last - understand the increased wear with wide semi slicks
 
Got those front issues under warranty so happy chap.
Ordered a set of RPX and stainless steel lines from HRNS-racing. they should last better than stock..
did not find a full set of RP-1 available in EU and from UK it would become more expensive due to bad exchange rate btw GBP and EUR.
 
499€ for complete set.

EBC Rennbremsbeläge RP-X, RP-1 passend für Toyota Yaris GR

Der Yaris GR von Toyota ist eines unserer Lieblingsautos der letzten Jahre- lange gab es kein Fahrzeug mehr, welches so einen Fahrspaß für vergleichsweise so wenig Geld bereitet. Auch wenn wir uns eigentlich auf BMW spezialisiert haben, mussten wir beim Yaris einfach zugreifen und schauen, wie...

Just need to bend the bracket a tiny bit, put the car on the lift and steer max right/left and you will see what I mean.

The pads and discs are among the best original brakes I tried on a modern car but they will wear out fast as they are thin and get hot no matter how you drive... with cooling it will hold out a bit longer.
 
Had another fun track session at Alastaro. Got strange warm coolant issue after car was shut down - need to discuss with my mech if that's normal.
Had now the boes seat first time on track and it is much better to drive in the limit - no issues with moving around during cornering so seat does its job + good headroom with helmet on. good alternative to bucket seat it is, though need to modify it as it does seem to fit perfectly from the rear to the stock frame.
