A4 B8 Forgestar F14 19x10 Question

[tuan0011]

Hi,

Interested in going 19x10 Forgestar F14.

Not sure what offset to go with, ideally would like minimal stretch i.e. 245 or 255. I am planning on coilies as well.

Looking at the stock wheels, I imagine the rear will require more aggressive offset to be flush with guard?

Help would be most appreciated, thanks.

Hmmm... Not too many 10" wide wheels on this forum yet, though Night&DayB8 is probably your best source of info since he's been running the most extreme wheel setups I've seen so far on here. Based on my rough measurements, you'd want ~ET40 to make them work. I'd imagine space is tightest up front, clearing the control arms on the inside and fenders on the outside. It can be done though! What do the guys at Forgestar recommend?

Thanks Blake,

It must be done indeed. Something about double digit width gets me going alright.
Alan@Modbargain is recommended by FStar that 19x9 +42 is suitable. I think they are going soully off Anthony's setup.

+40 seems about right, stupid question but does the A4 have all 4 camber toe adjustments (front trak model)? I am thinking I go 9" up front with ET 38. Is this fender flush aggressive?

Only the rears have camber adjustment. Toe is adjustable on all 4 corners.
By "fender flush" do you mean the inside edge of the fender or outside edge? Obviously the only way to have the lip of your wheels flush with the outside edge of the fender and not have (much) rubbing is to run stretched tires. Another factor to consider is how low you plan to go. My car is lowered to the point where there is no gap between the top of the tires and the fenders, but the tires are not tucking behind the fenders. This brings my camber to roughly -2 degrees on all 4 corners. I'm running 8.5" ET28 up front and I'd say the wheels are flush with the inside edge of the fenders. I probably have another ~4mm before I'd say they're flush with the outside of the fenders. ET28 on 8.5" is the same as ET34 on 9", ET40 on 9.5", ET46 on 10". If you want the lips flush with the outside edge of the fenders, those numbers become (approximately) ET24 on 8.5", ET30 on 9", ET36 on 9.5", ET42 on 10". Keep in mind, this is strictly based on my measurements and calculations. I've seen ET33 on 9.5" and it looked like the front wheels were poking beyond the fenders very slightly. The guy was stretching 235/35/19 tires in order to avoid rubbing and it probably would have been VERY close with 245's. For me, I think ET36 on 9.5" with 245's is the ideal fitment to create the flush aggressive stance without rubbing.

Lowering wise, as low as I can go to make the car driveable. Fender rolling is optional.
245/35/19 looks like the go. I'm not at all worried about the outside now given your above calc, which seems about right given the way LOU works it out as well and variances in lowering height can negate any problems. However main concern like you mentioned elsewhere is innerguard/shock/control arms..

Blake, what sort of clearance do you get with the coilover/control arm atm with your 8.5" +28 setup?
A bit of math given 1.5" difference to your setup and we could have a winner..

Thanks heaps.

I've never actually measured the inner clearance, but can fit my hand (with Mechanix glove ~1"+) between the wheel/tire and control arm. I'm guessing that makes the magic number right about ET40-42 for 10" front wheels to clear the suspension by a bee's dick.
