thanks! So whats the difference between early and late model fenders? seems like one is more desireable than the other?

edit: meant rear 1/4's

Early model rear arches leave more space for wheels/tires, especially as you go low.

Hi Mystikal,

I have spent about 20 hours of my life in this thread and have seen lots of good information so thanks already for that.

What I want to know now is a more of your subjective opinion on my setup.

Ordered RS reps in 16x8 +20 front and 16x9 +20 rear
Tires 205/50/16 nankangs all around
I also have some 5mm spacers I can put in the rear

My car is an 1989 vert with hard and soft top on H&R OE sports, 1 spring pad pulled in rear, and e90 hats in front.

I have not seen a lot of people run the 205/50 front and rear and wondering is going to look ok. I have spent the last few hours researching this and I gather that it will work fine I just want to know if it will look silly compared to say 205/45 fr and 215/45 rear which seems more popular (and far more expensive tire wise). Choosing the 50 sidewall was a bit of a practical gamble for me because I live in uptown new orleans and the streets are unbelievably bad, so I figure a little more tire height would help with comfort level of car. My civic running 195/45 on 7.5 inch rims beats me to death.

Nah it should look fine. More of a beefy look that may suit your higher ride height well. I say give it a shot.

Cool thanks man. How much lower do you think i could get away with using the 50 series tires. I could pull a spring pad i the rear (~5mm) and lop half or whole coil in front (1/4-1/2 inch). Then i gotta start worrying about tire hitting well/fenders up high? I have a skidplate so im safe down low.

I have an 89 325i on H&R RACE and Billie sports on e90 hats in front.
Question can I run 225/45/r16 on Borbets A 16x9 et 15 without roled fenders?

Thanks

Quick q,
did search, but still unclear.
16" kopi +5mm spacer + rear = vibration?
reason is for pure looks. flushness not hella flush
thanks

Yes, even at your current height my #1 concern is catching a fender when you turn the wheel. The combination of tall tires, lowered ride height, and soft spring rates mean if you have the wheel turned and dare go up a driveway you might rub.

If they're installed without special care, yes it's possible to get a vibration. You have to make sure the wheel and spacers are 100% centered before lowering the car to the ground. This involves carefully tightening the bolts in a star pattern and torquing them while still in the air (use the e-brake or leave it in gear). This is because a 5mm spacer pushes the wheel too far off the hub to be hubcentric.

Ah damn ok. I can roll em if it help. My driveway has a six inch roll over curb............ with tjat being said ill just go ahead wkth the roll hahaha.

Thanks! I like to make the world better, one fitment at a time.

Mystikal. I lub you. Turned out perfect. I did have a biath of a time seating those 205s on the 9 inch wheels. Fire just ended with singed arm hair so i used a piece of rubber sheet rolled up and held down on tire/bead. Kinda like bike tube method. Even that took me a little while to get right and actually be able to pull it out in time so tire didnt pinch it. Anyway.

Is it possible to fit this setup with adaptors of course or is it way to big for e30?

(Btw these are the Z3 M wheels)

I'm shooting for as much tire + grip as possible.

17x7.5 ET41
17x9 ET8
5X120
72.6 mm centerbore
225/45-17 F
255/40-17 R

[AE86]

15x8.5
+17 offset
205/55/15 Tires

Is this possible?
Can I use spacers (5mm)?
Is this possible w/ Billys & IE3's?
