Was a subtle dig from earlier on in the thread....

9.5 even +40 won't fit without decent guard work and camber on an 06 chassis.

XXR's were 8.75 btw

Since you're going all out just get some fender flares and 18x10.5s




Imo that looks like sex, minus the big wing

Go see Jarrod's car on SOWA he's flared it with 11 wide rims +7 offset... not my kind of thing

I missed the XXR bit but I wouldn't go for the 8.75 anyway. If I was going for them it would be the 9.75 and some bond on flares I've seen in the UK.
But every man and their dog seems to have XXR527's these days.

I asked about the 18x9.5 as I've seen the picture below and wanted to see the fitment for myself and what arch work if any needs doing. Based on what I've seen so far minimal arch work and -1.5 degree of camber is required on the rears. Just need to confirm that myself before I decide which route I'm going as I will definitely be needing more grip than the stock 17's can offer.

E85 is on the menu as I've got all the parts ready for it...all that is needed is the tune.

I'm getting it tuned on 98 then on e85...
I won't be doing a Flex tune as it's not possible on my OEM ecu and I won't be getting a Vipec/Link for a while... I'll be switching maps as required via Tactrix

What car do you have? All of the 16 bit ecu cars from about 01 can do flex now on the stock ecu. Do a search for Carberry.

ASG can't flex tune oem 01-07 ecus ...Kremer we are talking about "FLEX" tunes here... 01-07s can be E85 tuned, that is not a Flex tune.

I know there's some custom roms over the internet that allows it but they're not what tuners use here and aren't very reliable apparently.

The Carberry is a version of romraider which unless someone can prove otherwise is what what ASG use but call something else.
