I'm using the Arraut Motorsports 1.5" drop spindles on my '88 project car and I'm looking for info regarding front tire to front fender contact using the stock front springs and bump stops. I am using a stock size front tire.

For those of you that have installed these drop spindles, have you needed to modify the bump stops to keep from having tire to fender contact?

Thanks in advance for your input.

I don't have dropped spindles, but I did remove the front spring, shock and one sway bar end link to show where the 88 rests on the bump stops with some near stock diameter tires (205/50/16):




So if I had dropped spindles with by tires, they could possibly make contact with the fender on a really hard bump and I might need to raise the bump stop slightly (washer shim under it) or run slightly stiffer springs.

I would recommend you remove the springs/shocks on at least 1 side and check where they bottom out with the dropped spindle.

Where can one get slightly stiffer springs in the stock size for an 88 Fiero?

Cut down some 84-87 front springs from a GT. Or find another spring that is too long, but right diameter/coil wire thickness and cut it down.

Thank you Paul!

Any chance that wheel/tire combo is still around to get a diameter measurement off of it?
I'll measure mine again, I am pretty sure mine is just under stock diameter by around 3/8"-1/2". That might end up being a good thing.

I really should remove the spring and sway bar to check it but I'm not wanting to now that it's together...
I checked it with the fender off while I was working with the end link clearance issues and there was clearance from the top of the tire to the frame rail but I did not record how much...

My front wheel/tire diameter is 24.75".

Normally dropped spindles don`t affect the suspension because all it is doing is putting the spindle stub further up on the spindle bracket.
As far as tire rub it could affect that.

Yeah, I will get the diameter in a hour or two.

My tires are 205/50/16 and right at 24" in diameter on 7x16 35et wheels. If yours are 24 3/4", then your tires will be 3/8" closer to the fender than I show.

Depending on the offset and wheel width you might be OK as long as the tire is about 1/4 to 1/2" inside the edge of the fender. I trim my bump stops down so I only have about a finger width of clearance between the inner fender and the top of the tire.

Thank you again Paul!

It looks like I'll have some rubbing issues if I don't shim the bump stops. It's because the drop spindles I'm using put the wheel out another 1/4" and I'm only using a 38mm offset on a 17x7 wheel. They stick out noticeably more than stock.
