Going big on a wide arch FD3

leeroy_25 · January 17, 2008, 09:01:35 PM

I may have located some awesome rims for my FD project. If you have been following you will know it is being fitted with a burnout wide arch kit that is about 20mm wider than stock either side. The rims I have seen are 18x10 fronts and 18x12 rears... This is monster I know but do we reckon they will fit okay? The offsets are 25 front and 35 rear?
Let me know guys..

I reckon if I was running 18x8.5 and 18x9.5 I would need about 20 offset front and possibly 25 rear if that helps?

Thank you
Lee

Im useless when it comes to this but I find this helps me a lot. It will tell you how much more clearance on the inside and how far extended on the outside your new rims would be compared to stock :

Mine are 18x10 + 25 on the front. Run 255 and you will be ok JUST

Rears should be OK. With a widebody. Maybe the inner dimension will be tight but you could space them out.

I think Dcups has 11 or 11.5 on the rear no prob.

rextreme.. what front arches are you running?

i am running 18s 9.5j with 20 offset under stock arches with no kit.

really? slightly o/t but I was hoping to run ET30 9.5\'s on the front w/ stock arches.. what size do you have up front? (assuming that\'s a rear wheel spec)

What\'s fitment like? rolled arches?

front is et 35 and not a problem however if its lowered - mine is on hks coilovers it may hit the lip of the arch on track days and hard conering but this will happen even with a stock offset 17" i think by look of most rx\'s ive seen.

My et35s not rub as such but may catch the same.

Not rolled front and fully rolled rear but NOT flared as i think it ruins the lines of the car.

your 30s on the front i would say would be ok and you can always just have a quick roll done. with et20s they are extreme lets say so on the rear you cannot not roll the arches.

Guy\'s thanks for the feedback.. Sounds like I may be good to go!! Might be worth the risk!! Will let you know how I get on.

Thanks again..

I have Feed +20 mm guards.

Its the runing radius you need to worry about. I had to do some slight mods to the seams at the firewall.

Hmm. I just checked the offset.. They are actually 22 fronts and 31 rears. only a couple of mm I know but do we think we could still get away with it.. Has mega stretch on the tyres.. the fronts are on 245! and rears are 275..

Cheers

245/??/18

This may make a difference Should be fine though.

leeroy_25 · January 18, 2008, 07:50:21 PM

the tyres are 40 profile front and rear..
Cheers

these sound like supra or Aristo tyre sizes.

They are pretty big.

275/40 your speedo will be out a little.

Compare tyre sizes here.

put 265 / 35 / 18 normal rear size

then put 275 / 40 / 18

As long as they fit that\'s not a problem!! I can always change the tyres at a later date.. But they must be running a lot of stretch to fit the rims which will in turn effectively lower the profile.. (decrease the roling circumference)
