Is there any type of mod to allow 4th gen wheels on the front without Spacers?

Reason I ask is purely for aesthetic reasons. I don't care for the look of the brakes so far in the wheel well with the 4th gen wheels on it.

Well I can't think of any real easy ways to do it. You would have to create an all new front end basically since just spacing the rotor out somehow so it is closer to the wheel would require mounting the caliper in a precarious fashion structurally if using the stock spindle as its anchor point.
The route that I have thought about and would seriously look into if I were you would entail transplanting fourth gen front suspension. That way you could just use all of the fourth gen stuff on our cars. I don't think it would be all that bad to do if you are willing to put forth the effort. But I am assuming there is a reason that I haven't seen it done yet and that it won't be a simple bolt in. If you just took the shock, spring, spindle/hub assembly, upper control arm, upper shock mount, calipers, and rotors and made it work with our lower control arms and strut towers it should work out. You may have to use tubular lower control arms and have them custom made to position the lower ball joint in the proper location. But you would have a true LSA at that point with and take some weight off the front end at the same time.
Think of all of the brake, shock, and strut options you would have with that kind of setup!!!!!
A fellow MNFBC member and friend of mine is going to swap in an LS1/T56 combo into his 85 TA next spring/summer and I told him about this idea and he is interested. He has much more time and money than I do so he just might do it. One of his big deals is cutting weight off the car during all of his thrashing (to the point where he leaves some screws and bolts out if he figures they are not necessary) so this fits in well as it will lighten up the front end a bit.

That sounds like a good idea to try. I don't know if I have the skills to attempt that at the moment.
If you guys attempt to do it and succeed, don't forget to write a tech article and take lots of pictures.

i'm not sure i get your point..........?
you don't want to run an adapter because the brakes look to far away?
why not use a different style rim then. wether a rim requires an adapter or not won't change that aspect. if you go and have rims custom cut for your offset it can still look the same.
maybe i'm just missing something though, but i know the rims that i've bought were custom offset and the look of brake distance didn't and cannot change wether i used adapters or not.

I basically want the brakes moved towards the outside of the car so that they are more visible.

i think you guys are missing the point........that or maybe i am?
the design of the wheel itself determines what distance the brakes are at. unless you change the dimensions of the arm so that they come out further.
adding a spacer onto a wheel is the same as having a wheel custom made to a certain offset. it's just a better idea to have a solid piece when racing rather than 2 pieces (wheel, adapter).
my new rims had a 65mm offset in the front....wether i cut it to fit like my stock 16's or just used adapters the brakes never move and still look the same. so either change the design of your arms and relocate the brakes or change the wheel.

Since Zepher wants to keep his 4th gen wheels, then YES the only way to achieve the look he wants is to modify the spindles so he can eliminate the spacers. Basically, I think you're going to have fabricate entirlely new custom made spindles. Seems like a lot of work for a minor cosmetic change, but if you have the $$$ by all means go for it. It's your car.
