Toyota Auris Build Thread

[alexshock]

I did some market research and found a set of excellent used wheels!

Enkei wheels for Honda Civic Hybrid 2007 (they are Honda factory wheels).
Diameter: 15 in.
Fit width: 6j.
ET: 45 mm.
Center bore: 64.1 mm.
Bolt pattern: 5x114.3 mm.
Weight: 7.0 kg - great, especially comparing to my current setup!

They have almost completely same specification as Auris' 15in factory setup, except center bore which is easy to fix, so should fit perfectly.

They cost me USD 130 only (including delivery, wash and damages check).

Now I have to find good tyres until summer, to be continued...

Did some research about new tires...
Looking at Fulda EcoControl HP2 , I will wait for Michelin e.Primacy release to see real specs, but I don't expect any magic.

So, switching from stock Bridgestone to Fulda will gain 3.6 kg per corner (14.4 kg total).
Switching to Continental will gain 2.1 kg per corner (8.3 kg total).

Great stuff. I have the previous generation Auris Hybrid which I think has similar, if not the same, running gear. (Stock image below - though mine is the same spec)

Aside from the Grill block I've not done anything, as it is used by my wife as well.

I'll be following this one with interest though

Yes, true. Prius 3Gen, Auris 1Gen, Auris 2Gen and CT200h - all have the same powertrain.

But the rest is different. (But I know that I have same rear suspension with CT200h and some front suspension parts from Auris 1Gen.)

Just found that there are 2 towing hooks in the OEM package... I will keep only 1 Hope this is enough.
One hook weight is 570g.

I found some time to do wheels fitment check.

I had reasonable concerns... Honda-Enkei rim internal profile is very strange and narrow.
Honda Civic Hybrid rotors diameter is 262mm (without break caliper).
Honda Civic 4D rotors diameter is 282mm.
Toyota Auris rotors diameter is 296mm.

But it looks good after fitment, there is still some clearance.

I'm closer to the final installation

Finally!

I have bought a set of Dunlop summer tyres:
Dunlop SP Sport BluResponse 195/65R15 91H.

Real weight is 7.550 kg. (vs. estimated 7.200 kg.) per tyre.

And installed with Honda wheels.

So, total weight reduction (4 tyres + 4 wheels) is 21.640 kg.

BTW, new wheels have different lug nuts, which are smaller and MUCH lighter than Toyota OEM.
But I have not measured them in advance, so will not count it.

I was not able to sleep with this in mind... I did calculation for lug nuts.

So, according to spec, Toyota's OEM lug nuts weight is 80g each.
But I measured, they really weight 1369g in total (68.45g each).

Honda's OEM according to spec is 30g (real weight is not yet confirmed, may be some time I will get it). All together 30g x 20 = 600g.

Weight saving is 769g.

I'm thinking on installing flat underbody....

Today I have measured half of the car and bought a sheet of PP to prepare mock-up.
