I know this topic is beat to death but i can't find anythat that specifically answers what i want to do.

Right now I am looking at these wheels.

https://www.bbwheelsonline.com/enkei...77-570-4800gm/

And i plan to eventually lower my car by maybe about an inch.

Now for the super ignorant part. If i get the techno toy coilovers for front and rear and use those to lower it an inch? Are those wheels the right offset? has anyone used them before on their FB? Also i have a Gs that will soon be moved over to a GSL SE rear end and front.

 

The 0 offset of this wheel would be ok for non GSL SE suspension,pcd notwithstanding.

This wheel on SE suspension will have tire too far out into fender and will even with fender rolling cause fender/tire contact.
This wheel with @+33 mm off set will allow maximum tire size of 205/50/15-205//55/15 with no contact of fender or suspension on car lowered @1”.

I am running this combo on a lowered SE1.5” in front and 1.75” rear with stock strut tops.

You could use a wheel with less offset by running more negative camber adjustment in front coilovers.

 

These are the closest i can find for this wheel. The 38mm offset they have is 5 bolt :/

What about backspacing? Would these work?

 

Bump for response.

 

if you want some period correct rims, i can provide you with the number to my buddies at love20bee in SoCal. send me a PM

 

I follow love20bee on Instagram and they make me want every set of wheels they post.

 

the owner and crew of love20bee are my buddies. they have several RX projects that are coming to my garage to finish...just waiting to warm up in Socal. i cant work at 60* temp, too cold

 

Matt (owner of love20bee) gave me this rare 13x7 libre for xmas

 

I looked at their website and nothing loaded under "all wheels" Im also pretty set in those enkei compes i just need to know if any of their sizes will fit my car once i put the GSL SE undercarriage into it. Or these wheels.

Also i will be running Illuminas until i get coilovers for my car, so the wheels would need to work on both set ups ideally

 

Technically yes... they have a +25mm offset and 4.9" Backspacing. In a prior post i mentioned +33mm offset was perfect for fitting largest tires in front with SE suspension with no contact to suspension or fender lip. I had briefly considered this wheel but discounted it as it would bring the tire 8mm or 5/16" closer to fender and would mean running a smaller tire in front for clearance(185/50/R15-195/50/R15) and very likely rolling fender lip.
Considering you intend to lower the car makes a more exact wheel choice more important. I didn't want to run a smaller tire just to fit this wheel. You may not have an issue doing this.What are your intentions with this car?

At least one of those posts you read was mine,i did a lot of searching on here and started a thread asking specifics but only got vague responses and nothing i could use with certainty-dead end.. I looked everywhere for @1.5years and measured my oe wheels and needed clearance for sizes of tires i wanted to run and came up with the +33mm and had wheels machined to those specs. Cost some$$$ but i got what i wanted and they fit perfectly. I believe i have enough room to run a taller/wider tire with no contact on my lowered car.

 

The car is my current daily and it will be used for autocross as well until i eventually get a second set of wheels for autocross specific rubber. (so a year or two, i have other mods before i go down that route) what about some space to get the fit more perfect? a couple of mm shouldn't be a huge deal right?

 

Couple millimeter is just under 1/8". 8mm is 4x that at 5/16". That is a bigger deal. Are you asking about some"spacers"? to get the fit more perfect? In this case no,any spacers added between rotor/wheel push tire/wheel further into fender,the opposite of what you need. That +25mm wheel you're looking at with a 1/8" spacer between rotor and wheel is now a+22mm offset wheel. A 1/4" spacer makes that a +19mm offset wheel. The only way a spacer could be used to correct offset is to fit a wheel that had less offset than needed and would have tire/wheel contact on inside of spring/strut and using spacer would move tire/wheel out further toward middle of wheel opening. Understand the concept?
Fender rolling can relieve some of that,however no 2 cars are the same and no 2 tire manufacturers have the same profile/dimensions in the same size,furthermore you're not saying what size tire you want to run and this is as important a factor as the other parameters in wheel size/width/offset decisions.
I know some are ok in using spacers to correct offset,i have in the past,never more than 3mm and don't use them anymore as i found wear patterns on rotor face/spacer/wheel that show pieces moving around under cornering forces with sticky tires and symptoms of lugnuts not holding proper torque over time and no,overtorquing lugnuts in attempt to keep wheels tight does nothing but warp rotors and shorten wheel bearing life.
I arrived at the +33mm offset figure with some math to put the wheel in the center of fender opening with enough distance on suspension side to give 6mm of clearance between strut/spring and just enough room to keep tire inside fender to accommodate lowered car at near full spring compression under hard turn..

Will try to dig up some pics of my car showing how close you can go with no fender contact,also try to find a wheel fitting chart to help you better understand wheel backspacing/offset.




See in 1st pic,backspacing is dimension from inside mounting flange of wheel to backside of rim lip and offset in a wheel is how far the hub is cast in the wheel away from centerline of rim. The more the rim is placed outside the hub center the more/lower offset the wheel is. A non SE suspension on 1st gen accepts a 0 offset wheel perfectly. An SE suspension has a wider stance that pushes it further out and needs a higher offset wheel to keep rotating assembly in center of fender. OE SE wheel has 4.5" back spacing and +40mm offset to achieve this.Hope this helps you understand better
2nd pic 15" x 7" +33mm wheel.
3rd-4th pics show relation of wheel/tire to rim lip.

 

I'm planning on running the same tire size my enkei 92s have (4x110 bolt pattern) 195 50 15s.

 

thanks! and nice shoes! i have a pair like that, in walnut

 

You mean,as in wood,like these?

 

That size tire will probably work on +25mm offset as it will be slightly stretched on a 7" rim and that will pull sidewall down and away from fender. Your intent to eventually autocross the car will have you wanting more rubber under the car and you'll be back to sourcing a proper offset wheel to accommodate those tires. The larger rear tire fit shouldn't be a problem with a possible fender roll needed for the +25mm wheel but the front will require pulling and rolling fender and if lowering with coilovers,running couple degrees of negative camber to pull strut assly/wheel/tire inward away from fender lip. It will not be 100% known to work til tried.

 

First of all i have decided to NOT lower my car... i have WAY to many speed bumps around here lol.

Also, if... i understand correctly from all of this, could i just machine the back of the wheel down a bit to get a higher offset? i have acces to a lathe so if i took 8mm off of it from the back that would give me the 33mm you have right? Is this how you had it done?
