GR Yaris What did you do to your GR Yaris today?

Tws rs339 8.5j (+45) rims and Bridgestone RE-71RZ in 235. Since that's the grmn size and Toyota Japan offers a gr parts rim/tyre combo in that size/offset it seemed like the right choice for a road car. Does seem like most go right to a 9/9.5j on a 255+

Massive upgrade over the stock ps4s in both feel and performance which were just too soft for any hard driving.
Kept the factory bbs rims for winter on michelin x-ice. Got a few things coming next week

I am on 10j with 255 and for me optically it seems like right amount of rubber and wheel. the stock size looked lost insight the wheel wells.
I agree with you on the ps4s. the tire was hyped by seemingly every car journalist out there but I was disappointed how weak the side walls were. I only keep the stock wheels on when inspection is due for the car :cool:
 
Went back to the summer wheels, I'm gonna miss the Sparco's, they really grew on me and made the car look a bit more "mine", if that makes any sense 😄.

Changed the plugs at work while I had a quiet half hour. 45,000km on these plugs. Definitely the right time to change. Will start changing every 20-30k in the future. Picked them up for 17 euro a plug.

Start up and idle way smoother and not lumpy as before. Looking forward to the drive home.

I got some lumpy idle sometimes and had a few harder startups too. Just tried some liqui moly direct injection cleaner, let's see if it improves it a little, otherwise I have a set of hks spark plugs ready to go.
Read somewhere in the forum the maintenance schedule had some injector cleaner at every 20k km if I recall.

@Armijs has been banging in fuel additive to keep things tip top. I think I might start doing same. Plugs are a piece of piss to do if you have a long thin walled 14mm 12point magnetic plug socket and a 150mm extension bar. Torque specs are 18nm for plug and 10nm for coil pack. To move the plastic trunking for access to coil 2 and 3, remove the one 10mm bolt on right securing it, and it clips off the bracket of the left with 3 bolts (you don't need to remove bolts on that bracket)

Always has been. Had Iridium plugs before on a Colt CZT which had them scheduled at 100.000kms which is overly optimistic. Just change them yearly and be fine. I dont know if the Rotheli engine blown up was due to spark plugs but why risk it for a maintenance part which costs a fraction of a new engine.

Thanks mate. They are Rallyflapz, not to difficult to fit other than getting the rear ones angled right. The quality isn’t too bad. @Sticky does the graphics https://www.chevronsdirect.co.uk/collections/toyota-gr-yaris

Thanks for the plug (y)

Did you replace the rear glass to fit the wing?

It's on my wish list, just think it's a bit of a ballache removing the bleeding window, and was wondering if it is an absolute must, or if it can be 'chanced' without a change.

I may have to look into creating some decals to fit into the GR-Four recess on those end plates.

No need to replace the window! No need to chance anything either, all the correct parts required for an “as factory” installation are available.
