I am thinking to buy the 13" CXRs
I really like the back to be wider than the front. I also really like the looks of the CXR 8x13 in the back with 7x13 on the front.

The good news is that compomotive makes them the right offset (I think is ET35)
Do you think that the rear ones wouldn't fit? Please note that I am planning to use the car only on track mostly with slicks.
That way I believe the car will handle better on the corrners but with the cost of making the car a little bit slower but the above does not mean that I dont listen to other people opinions to the subject. Let me know yours please.

"bigrich" has a set of these. You may wish to u2u him.

As does Athoirs as well.

Will they fit over the rear disc setup?

They do on the MNR....

As long as the MNR rear disc setup is from the sierra, it should be the same.

watch those 13" with rear discs, I suspect they wont fit, if they do they will be very very tight. I think the safest bet is 14"....

205/60/13 on the rear are the same as 195/50/15 for gearing so wont affect top speed or speedo accuracy, they fit over the standard sierra disc set up with a slight tweak of the handbrake mechanism, or if your a sadist and want some work then they can be persuaded over wilwood handbrake calipers, but its not a straight forward conversion.

Also if your looking at 13 inch rims then there will be a new 13 inch team dynamics pro race 1.2 available very soon with a sample wheel to look at hopefully at the autosport show.
Mac#1 have commisioned the first production run so may be worth a look as an alternative to cxr's

Hi Guys,

Yes and No

I have 13x8rear (245's) and 13x7'sfront (205's)on my indy

fronts are not a problem but the rear is.

even with max offset they will not fit over standard sierra disks AND fit under the arch. I had to go to fiesta (front) disks on the rear and turn down the hub to get it to all fit. also the caliper mount is now part of the rear upright. oh and the shock mount has to be moved inboard as well! You know the more I talk about it the more I wondered why I bothered!
Ill try and get some photos for you tomorrow

Andy

I have drums in the rear. And I will upgrade to 4 pot in the front. Would they fit?

I've got rear drums, and wilwood 4 pots up front. They fit fine for me.

Ok guys thanks for all the advice!
I order them today
compomotive 1370 PCD 108 ET19 front
compomotive 1380 PCD 108 ET19 rear
with tyres
Michelin slicks 20/54/13 soft front
Michelin slicks 22/54/13 soft rear
Hopefully will fit under my arches (I have the wide cycle arches in the front) I am not sre if they fit under the rear arches though.... will see...
Should be here in 3 weeks

Mmmm Et 19 might be ok on the front but on the rear I think they will stick out about 1"

Good luck anyway- they are very good and light wheels!

Do you think that ET19 is too much for the rear and will cause any problems?
I dont mind to modify the rear arches to make them fit but I dont want to modify anything else except the wheel arches.
I am preety confident that in the front I wont have any problems other than modify the cyrcle wing stays (supporters however they called anyway..)

Sierras are Et 38 if i'm not mistaken

yes sierra is ET38. But does this mean that ET19 would be not appropriate?
It is duable?

I am sure you have, but if not go to the compomotive web site

http://www.comp.co.uk/info/technicalinfo.asp#

and have a look at their diagram on how to measure offsets. then get the steel ruler out and measure up the car, its the only way. As I said I think they will stick out about 1" but dont hold me to that.

Andy

yes that would be ideal (to measure my car) but the car is in Greece and I am in UK. I just asking if anyone tryed before and know that it is actually fit.
Thanks for the info though!
