69 Camaro 2" Drop Spindle Dilemma

[Wrobotech]

Hi Josh,

Glad to hear from you - I'm researching control arms and seriously considering the Strong Arms. Emailed ridetech sales with questions - waiting for reply.

Just curious why tire diameter is a potential problem? Some stock tire diameters were closer to 27" The MT tires on my car are 25.70"

I measured the wheels they are closer 4.75 BS The inside of tire just barely rubs the frame when its on the steering stop. Seems like more backspace will cause tire to rub the frame and reduce turnability.

The ride height is about 25" measured center of front wheel opening/fender.



Another piece of the puzzle worth mentioning is the TRSD disc brake kit relocates the wheels out 3/8" on each side.

Let me know if you have any questions or need more info. Look forward to hearing from you soon.

No problem at all, I'll be happy to help out. The brakes adding to the track width and possibly having the wrong backspace wheels could definitely be your issue.

I read your tire size wrong earlier, it wouldn't be that big of a deal, that's my fault. One of the reasons I believe it's a backspacing/track width issue is that when we built our Streetgrip kits, we had the kit on a '69 Camaro that ran 235/45-17's on the front (25.3" OD). Our fender to ground measurement at ride height was 23.5" (1.5" lower than yours) and the car had full turning radius with no rubbing at all.

If you'd like, you can email me directly with the questions you have! My email is [email protected]

By the way, your car looks very nice!

Thanks for the info and compliment Josh. I will give you a call later today.

Not necessarily.

I have an explanation below for you as to why they're not all problems.

Correct. At this point, it sounds more like a wheel fitment issue. That's also a little bit taller of a tire diameter than we see these days.

The drop spindle with our kit is designed to do two things:
- Creates negative camber gain because of the taller design
- Lower the car 2"

Because we're using this spindle to get the lowered stance instead of a shorter stroke shock, we gain ride quality and handling by not sacrificing shock travel. It's all set up around factory track width as well. The only chance of someone changing track width with our kit is dependent on what brake kit they choose (which could also be part of your issue with your current setup).

If you're wanting to change to a tubular arm setup, look into our Strongarms, spindles, and coilovers. On the control arms, we've moved the balljoints for more caster, put in delrin bushings for smoother movement of the arms, and have the drop pocket so we can run the longer shock for a better ride. From everything you're saying, I would venture to guess is more of a backspacing/tire height issue though. I still believe that would need to be addressed as well, especially if you're wanting the lowered stance.

If switching to a disc brake drop spindle from factory drum brakes, the wheel will be moved outwards 1/2" to 5/8". The drum brake hub has less outward offset.

Hi David,

Yes indeed another 3/8" with the TRSD kit installed on my car. This part of the project reminds me of a mathematics story problem

Hi guys,

Reading this thread just gave me a bad feeling in my guts.
Although I don't have a touring car, I am in the process of bringing my 69 Camaro that I used for drag racing and putting it back onto
the street.
I have a CPP manual disc brake setup on my car and I just ordered 2" drop spindles for it.
I'm running a 15 x 3.5" rim up front on 28" tall MT tires.
I'm reading in this thread that the OP can't turn his wheels without hitting the fender.
Can anyone tell me if my setup may or may not have the same results as the OP?

Thank you
Bruce
