Having seen the 18x10 et15 on the car I'm 99% sure that et25 will be fine

I just fitted some BBS ch's 18 x 10 et40 with a 20mm spacer ie et20 and it only just misses the front suspension strut by 3mm. :banghead:

[_Nathan_]

3mm is fine isn't it?

Sure I'll find out if I've made yet another expensive mistake soon enough, I'm only running 250 wide tyres too which might help?

Lots of people in the US running 18x10 et25 up front....

[DuncanR]

yes i know but 9.5J rear CSL rims rub on arches on road with -2 camber

9j rims with 265 tyres wont be much better so i would def go et30 rather than et25 on road biased car

And thats the way I am going, finally ... having watched all the options flying about on here, and not really having a scooby about whats best,:banghead: I have bitten the bullet and ordered 4 new TD 18 X 9 with ET30,I already have 10mm spacers:thumbs:. And if the 265 dont work on the front I will fookin make 'em work !! even if I have to put them on a Lathe and turn them down !:supz:.
Any additional speed, traction or road holding i might need will have to come from my bollocks ! ... so mote it be !:clown:

[DuncanR]

pays for my new rims in 2 sets of tyres:thumbs:

So buy 2 more sets of tyres ...and get another set of rims free Shim !:hahaha::thumbs:

Dont do the Foxhole on a full stomach, and your wallet on board then mate !!:thumbs:

[DuncanR]

will be running 245 up front and 265 in the rear so wheel swapping won t be possible for me.

Which make 245 ? obviously not Cups

[cantfind1]

Which make 245 ? obviously not Cups

Am thinking about kumho's they have had good reviews the v70a. Am I right in thinking I need a 245/35R18 or a 245/40R18. Will be going for the hard compound, they do a medium as well.

For the rear it will be the same tyre with 265/35R18 in hard compound, thats the only size they do in a 265.

I struggled to find track tyres in 245/40. Not sure kumho make that size either.

Toyo do the R888 and the R1R in that size, never run them so cant comment as to performance !

[cantfind1]

Yes you are right toyo do the 245/40, kumho don 't do the 245/40 only the 245/35.

Any one know which size is better for keeping wheel circumference right?

Come on shim im waiting!! :whistle:

[shimmy]

Come on shim im waiting!! :whistle:

:birdman:

OK good point will defo be waiting as my car is at simpsons at the moment. Say hello to it for me!

sweet! Carbon black one with no roof screens or interior! and half a cage. :bigcry:

it looked sad so i gave yours and Nathans a cuddle:thumbs:

I also still have some doubts of the possibilities of running a 265 up front. But certain it will be fine.
So... I will listen out for the all clear from Shim too, so let us know. :thumbs:

so i had a trial fit of the fronts at Simspsons last week. Just to refresh your memory i have new front rims 18 x 9.5J et37 (et15 rears) Volks running 265/35/18 Michelin Cups on Intrax Ik2 suspension

The goal is to run these on both -2 and -3 camber (road and track) without rubbing. The difficult bit will be to get the tyre and rim to sit between the arch and strut and not touch either on both settings when the adjustable camber plate is used.

We fitted the rims first on road settings -2 camber with 12mm spacers. It seemed like the tyre was far too close to the arch so we tried 5mm spacers. This fitted perfect with both looking ok but spacers were not hubcentric so it was thought that i may get wheel vibration. So then we tried NO SPACERS but the tyre was to close to the strut spring. Not touching but close. Simpsons suggested reducing the size of the follower spring on the Intrax therefore lifting the spring base up and making more room.

So after all that the et37 rims fit front without spacers. I dont think this would be acheivable without a/m suspension but with maybe 3-10mm spacers other compromises may be possible. I will try 3m spacers to give some more comfort room between strut spring and tyre i think. so running et34.

My gut feel on OEM suspension and a/m suspension is that et32 is about right on 9.5J fronts. et30 should be ok BUT et25 might be too tight unless you have OEM suspension in which case you might have more roomunder the arch

I thought you opted for ET32. Anyway glad things are working well with the correct spacers. Only way is trial and error in which will have all benefitted from you, so.... Thanks. :thumbs:

P.s Just about to go collect my 18/ 265 Cups.

[shimmy]

whilst i was weighing the suspension i managed to check (nervously) the new rims and tyres

results

VR G2 are 2kg per wheel lighter at the front and 2.4kg lighter at the rearm and this is with 9.5J at the front so a good resultm even better than i thought. This was measured with tyres on as well and 18 inch tyres are 0.5kg heavier than 19 inch

overall unsprung weight saving 8.8kg :smokin:

cost.............................never mind :whistle:

[_Nathan_]

lol, I did a cost per kg spreadsheet to work out what to do first

PS. When you gave it a cuddle did you feel the weight of the doors
