Wheel spec check

[dogbucket]

Just wanted to run this past the experts to check I am not making a massive error before ordering.


Compomotive MO6's

Front 7x16” ET25 4x108 Silver
Rear 8x17” ET35 4x108 Silver

Tyres thinking of Toyos

Front 205/50 R16
Rear 235/45 R17

Did not want to go too mad on the front in case it tram lines etc.

What do you think?

Just a question but why wouldn't you go 17" all round?

Then you could use 215/40/17 x 7" front and 245/40/17 x 8" rear which gives an almost identical rolling radius and in my experience actually gave an improvement in tramlining thanks to the use of better rubber. I feel it looks more modern and balanced that way although I know that's not a universally held opinion.

The offsets are the thing you absolutely need to get right to avoid any nasty steering effects. It needs to be ET25 front and ideally ET33 rear although I and most people use a ET35 rear as they are a standard size an 2mm on the rears makes virtually no difference to handling or component longevity.

My car drives so much more nicely with this set up. Can't remember the price I paid but it will be in the blog on my profile.

Hope this helps?

Edit: Sorry - I see you already have the offset information spot on!

Looks OK. The way I read it you may have trouble with your chosen colours but that's small fry. Don't forget the centrebore dims and possible spiggot rings.

Thanks both.

Compomotive have already quoted for Silver so that is ok.

I agree the size is a subjective thing and I fall in the camp that thinks the smaller front will retain the original look more.

I will check center bore sizes as well. But spiggot rings?

These are just rings of aluminium or hard plastic, that fit over the spigot on your car and then have a proper fit with the spigot hole on the wheel. If you don't have the spigot taking all the weight of the car, chances are you'll break one or more studs when you drive the car hard or have to brake hard. Remember the wheel nuts are simply there to hold the wheel on, NOT support the weight of the car. Also, as there is nothing to centre the wheel, you'll notice the wheels go in and out of balance because as you drive around, they'll move around on the hub.The wheels are a kind of multi fit for Ford or Peugeot etc

Hmmm, here goes.

So far so good.

Actually the wheel nuts produce tension in the studs which push the wheel onto the hub; the resultant friction then holds the wheel on. Scary isn't it?

The nuts will centre the wheel. This is why it's important to buy wheels with the correct PCD. Wheels with a close PCD will fit but the nuts won't centre them correctly and will bend the studs slightly.

As above shouldn't happen because the nuts should do the job.

They're the Ford 3" square.

In short: if the centrebore isn't spot on the spiggot rings are a useful centreing aid.

Have spoken to Compomotive and they have recommended 63.4mm centre bores which is what they have done for Chims before. I measured 62/63mm eariler so that seems about right.

Hopefully get them ordered next week after pay day

Will have to get some new nuts as they will be more visible with these wheels. I am guessing just Ford fitment M12x1.5?

[SILICONE KID]

There a very nice wheel but very expensive...I looked at them before the pro race 1.2...The Compomotive MO6's suit the Chimaera .

I have these wheels (as you know d'bucket), mine are sized for tyres 255 Fronts and 225 Rear. With Toyo TR1s, it didn't feel any different to the std sizes in terms of tramlining. Aplogies for not knowing the precise sizing as I wrote it all out on a bit of paper I can't find for the life of me.

I *think* that wheel size on the rear is 17x9 with 255/17/40, and front is 16x8 with 225/16/45.

Basically I used this http://www.rimsntires.com/rt_specs.jsp to find the sizes for width of wheel for these sizes without being miles out from the original rolling radius before I ordered.

I'll find out for sure once the car's back from Dan Taylor's.
