So I'm going to get the Racecraft 2" drop spindles but I felt 2" is too much. I'd like to raise the front a good 0.5" after doing this for a total of 1.5" drop. I already have a new spring isolator with 2 year old MOOG 5662 springs.

How would I go about raising the front height 0.5" more than it is now? Adding a second spring isolator? Are there spring spacers I can buy? Buying new springs?

I'm fighting for the perfect height but without screwing up suspension geometry. Raising the height might change the angle of the a-arm as well. I know that the angle of the a-arm should be slightly higher on the bushing side compared to the ball joint side, but not too high.

Thanks!

 

weight jacks! or buy universal springs and trim to fit, but thats a pita...

you may be able to find a spacer for on top of the spring, they are 5.5" OD springs up front, so look around. try some circle track shops/site or ebay.

 

I also felt 2" would be too much for street use, so I am running weight jacks with my drop spindles. I have 9" springs up front and have my car sitting at 25.5" from the ground to the fender lip with room to raise or go lower. Weight jacks are also nice because the springs can be installed without a compressor.

 

Take weight off the front end, that'll raise it

 

Damn weight jacks lol.. They add weight which would negate the weight savings of the drop spindles.

lmao i'll just drop and LS1 in there and call it a day haha.. i wish

Found these .. Not sure if aluminum is the way to go if the car is used on the street (pot holes anyone?) or if Rubber or Poly are the better ways to go? I think that 0.75 inches is good that way I only lower the car 1.25 inches total which is pretty good in my opinion for the street.

 

i suppose that would work. i dont see any issues with strength as far as potholes go

as for weight, the drop spindles are unsprung, the weight jacks are sprung weight, so they are not exactly counteracting each other. they are also weight down pretty low int he car, so they are not as bad as adding weight to the roof. besides the couple pounds they do weight will be easily offset with other, more important weight reduction areas, like the front bumper support, hood, and other weight ahead of the wheels and up high.

If you choose to install the jacks directly to the k-member, instead of using ground controls setup, that will be a little lighter than the GC setup, and if you use aluminum spring plates, a little lighter still. Just do it. Its more than worth it. Once you have the rate you need, adjusting the height to when you need it is simple, you dont ahve to take the spring out and cut it, and if you decide to have the car scaled and the corner/cross weights set, they will greatly help that too.

 

Where is the weight savings in a drop spindle? They probably weigh more because they have to be taller for the "drop"

Not to mention the weight of the jack is offset by the fact you have to run a shorter spring

 

That's true about the shorter spring.. Probably equals out come to think of it. Won't the shorter spring make the car bottom out though?

The drop spindles are 'advertised' as being 4.2lbs lighter per side of unsprung weight (not sure if that makes a diff in the steering feel because the spindle turns with the steering and since it's lighter maybe it makes steering feel easier and lighter?).

I have no way of verifying this right now but I will do it once I purchase them.

My personal opinion is that i can just use the MOOG 5662's i have on there now and just add the spacer+drop spindles and be done with it. I don't see myself adjusting height and all that primarily because I don't race with the car all that much it's more of a fun thing with friends every now and then, and also adjusting the height will mess with the camber and caster and aligning this car takes alot of effort with the tech at the place I go.

Thank you guys for the help!

they are lighter...., significantly actually

 

you need to find a new shop

 

Are you talking about fabbed spindles? and are you comparing those to spindles with the old caliper ears cut off? I still dont see them being that much of a difference, but I dont have a scale.

 

yeah, the racecraft spindles are fabbed.

I dont have teh racecraft ones to compare too, but they are advertised as being a few pounds lighter each.

 

Haha I guess so.. Funny because there was a guy who owned a thirdgen there and I told him the strut to spindle bolts that I installed were adjustable and Mr. Knowitall said that he was 150% sure they weren't. Then he left and I told the tech to adjust them now lol and then he did it and it changed the camber, SAI, and IA to much better and even numbers.

There's just too many aftermarket parts on my car for any tech to understand I guess. And this is the #1 shop in the city of Montreal for alignment with state of the art equipment. Kinda sucks I have to stay there for two hours with the guy and explain to him how to do his job.. Sigh...

 

I'll compare the two as soon as I get em. Damn I'll have two sets of spindles now lol. One for stock and one that is PC black but modified for LS1 brakes. I'll compare the RC ones to both actually just for fun.

 

Leave your height the way it is! The car handles great and doesn't have any issues that low riding cars do.

 

Haha thanks Reid! You've always been a fan of my height

I keep going back and forth about the height as there are advantages and disadvantages to both.. For now, i'll leave it as is
