Back Space for DSE Camaro?

[icemanrd19]

LOL split it. 5.6125

Do you have any rims sitting around that will bolt up? The wider the better. If so i have an idea

Just the ones on my car now. 17x9 with 275s, 5" back space

To far in? If so add 1/2 spacer to the rim and kick it out. see how it fits on the inside of the inner fender. Keep adding spacers till you get the inner position perfect. Plenty of places sell cheap spacers or you can cut down some pipe to kick the rim out. After that you know the backspacing you need and then order your rims

Make sense?

I was also going to suggest: you are better served to have too much BS vs. not enough (at least in small amounts). When I was in between numbers, I went up (more BS) and realized I could use a 3/16" to 1/4" spacer if I needed to. Which is exactly what I do now (1/4" on both sides).

I'm about to get a new set of shells from Mark to stuff way-too-much front tire under my Firebird. I'll be doing the same thing with the new setup as well: running a spacer to get it just right. I am struggling with my outer shell width. I only have one choice for the inner since my centers are already cut...

Good luck.

What are you running right now?

I like idea of splitting it lol...5.6125, never crossed my mind lol...I would really like to see how close other sec gens run to the lip

I don't use the DSE components, so my numbers won't help you any...

Not DSE specific, just how close people run their tires to the fender lip

[icemanrd19]

Im telling you. Put your 17" rim on there and add spacers till the inside part of the rim and tire is your liking. You know that offset is 5". That gives you a darn good starting point. If you have a extra half inch of clearance on your current rims on the inner half to where it would be comfortable then you know your backspacing. The inside lip to the hub is the same for all rims if the backspacing is the same. Doesn't matter if you have a 15x6 with 5" backspacing or a 18x12 with 5" of backspacing. Both inner part will be in the same area. Put your old rims on

I took some measurements of the tool and about 13" end to end. I so much feel 5.75" is the right number but everyone it seems are running 5.5". I'm missing something.

All my tool pictures are set at 5.75" BS

You can always run a thin spacer if you need. We have several car builders that will use thin spacers to fine tune a fitment. If you feel that 5.75 is best and DSE recommends 5.5, worst case is that you will need a .250 spacer. We can make a nice spacer if you want or you can get one from an autoparts store. Many places have them available.

Dude, you're overthinking it. Looks like you're getting your wheels from Forgelines. Just use your wheel fitment tool and make your measurements, or consult with Forgelines on how to measure it, as others had stated already. DSE specs are what they use on their cars, but most of everyone on here will know that these cars were never the same, even when brand new from factory.

We followed DSE's specs on the front wheels on a 65 Mustang with Aluma Frame. We ended up adding a small spacer since the wheel had too much BS to our liking.

For the wheels on my Firebird, I added some additional BS from the recommended numbers, just so that I can fine tune the fitment.

I agree, but it seems nobody has veered off from DSE'd reccomendations which makes me question myself. I have the tool and Yes I am getting DS3 Forgelines. Looking to see if I can get pictures of other people's fender lips to see where the majority tire rest on their car.

[badazz81z28]

Seems a lot of people are not using DSEs front frame recommendation. Why is this? Are you all hitting or rubbing with 6.5 BS?

if you do any autocross or racing running thin spacers allow you to adjust track width....I run spacers front and rear and by simply removing or adding i can make the car push or oversteer

I'd go towards the cautious side. All cars are different. You will find that once you load the wheels and suspension it will pull in anywhere from 3/16" to 1/4" which is why we use test wheels.

If it were me i'd run the 5 3/4" and run spacers to fine tune it. 5.5" but I would smooth the lip and open up the outer wheel house.

[badazz81z28]

I wish I had mock up rims to install! The suspension is loaded with weight on the axle in the pictures.. I wish I could find folks with the same axle width to compare. Where is the tire supposed to end up? Inside that lip? Or where it does with 5.5 and trim that lip?

[Nine Ball]

You are doing it the right way, measuring for fitment. I would not personally suggest planning for spacers, that is why we take careful measurements - to avoid doing that. These older cars vary too much to just use published data. Quarter panels that have been replaced might stick out further than original. Right and left sides can vary a little. A lot of factors.

Two things I noticed:

1. Could you flip those grade-8 bolts on the lower shock mount, so that the head of the bolt faces the tire? That would give you a little more clearance.
2. It appears your quarter panel on the driver side was repaired by just laying it over the top of the original quarter panel. I see two lips there. I'd be tempted to cut those down, or roll them, on both sides.

Just measure carefully, and pick the backspacing that is the worst case from either side. That way you know that both wheels will fit both sides.

Curious about what you ended up going with and how it worked out. I'll be needing to purchase my wheels and tires soon and am looking for examples of what has worked for others with similar set-up (I too am 56.25 total).

I went with DSE Specs. Trimmed the fender Lips and actually rolled them for peace of mind.
