PA racing.

 

Damn 100 pounds is a lot how much did the brakes and spindles cost?

 

Id like to know also!

 

This is great information!

Thanks

 

How does the drop help?

 

Is the spindle ONLY just 6.5lbs ea. like claimed?

 

Do you know if that is $550 per spindle or $550 for a pair? Those are looking nice and I might go this way.

 

Hey guys my name is Mark from Racecraft Inc. our spindles are $550.00 for the pair and are in stock. If you guys have any specific question about are spindles or any part for that matter let me know. I will keep an eye on this thread and help as much as I can. We will have a 2" drop spindle mount spindle available in about 5-6 weeks.

Thanks, Mark

mark,

compared to the santhuff or PA spindles what are the weight differences between yours and theirs?

i know you sell santhuff and your probably familiar with the PA product,

would it be possible to only get a 1" drop or no drop on your spindles?

will the cost be any higher on our spindle mount spindles?

Thanks,

Tyler

 

$550 a pair is a good thing! How do these hold up to light street duty? No road racing but the occasional drive around on the weekends?

 

Compared to the Santhuff and Pa spindles our spindle is probably the heaviest of the 3. The Santhuff is the lightest, but is not a drop spindle and requires a spherical bearing control arm (which we make) so if you are lowering your car you will still have an angle problem at the a-arm. I can't really comment on the Pa spindle because I have never seen one, but they are supposed to be 6.5 lbs? Our spindle is designed to be a factory replacement spindle that lowers the front of the car 2" without changing factory suspension geometry. It’s constructed from mild steel plate and DOM tubing. All of the parts are cut on CNC machines, the spindle is made of 4130 and is pressed into the mild steel body, then tig welded on the backside. This is the same design we have used since 2003 when we stared making Mustang drop spindles, to date we have had Zero Failures. We are awaiting new CNC equipment, which should be here in the next couple of weeks that will enable us to make all of our parts in house. We have 2" drop spindle mount spindle parts being made at are machine shop vendor right now, those will be coming soon, these spindles will weigh about 6.5 lbs. The reason our spindle weighs 10.8 lbs is durability and weight of the car. Most of are customers race 3000 lbs. plus cars on little tires which is a formula for wheel stands. I want our parts to survive this situation, which they have with flying colors on our Mustang stuff so, yes they could be lighter, but I don't want our customers to miss the next round because of bent or broken parts. If you have a light car and need the ultimate lightweight set up, we will have that too with our spindle mount spindles. As far as different drops, maybe in the future, but not at this time. Spindle mounts will cost the same as the current spindles.

It lowers the car 2" but the a-arms stay in the same location as stock, the spindle itself is placed higher so your car ends up lower but you don't have the screwed up geometry when you lower the car.

Dropped spindles are "the way" to go when you want to drop the front.

 

I understand all that, what I'm getting at is

1. Aerodynamics
2. Chassis dynamics

Lowering the front changes your CG and I would imagine affects your rear suspension geometry as well. Actually I'm pretty sure it does.

Does it help keep the front planted? Loading of the rear wheels during launch? Tie Rod to spindle adapters tapered?

When you take into account the cost of front Strange Eng. 4th gen brakes and the cost of Racecraft front spindles and 3rd gen brakes it's only a few hundred more. I just want to know the benefit.

I'm on the verge of buying the brakes and manual rack, I'm glad I saw this thread, and want to make sure it all works together and there is a benefit.

BTW, I KNOW it's A LOT easier to just call Racecraft but I'm sure the membership can benefit from this information on this forum.

 

I will throw this out there, but I wish more people would post actual weights because just saying something saves 30lbs is WAY too vague and hard to compare the different options.

My stock cut front spindle WITH the strange spindles installed (off the 4th gen brake kit) is only 14 lbs. So now you can compare exactly what you save with the aftermarket spindle mount compared to the 4th gen brake kit. The gain isnt as big as most are making it out to be, atleast in comparison to the 4th gen strange setup.

 

This is from Racecraft's site. Maybe I'm just retarded but I need further clarification on the weights

Racecraft Inc. now has a 1993-2002 Camaro 2" Drop Spindles in stock and ready to ship. Theses spindles are TIG welded in our fixtures, using CNC and Hydroformed steel components. These spindles also offer an astounding 42.1 lbs (these are true numbers not advertising hype!) of total weight savings over stock when used with the Strange Engineering 1982-1992 4 Piston Drag Kit (P/N 330010).

Spindle weighs as shown 10.8 lbs. This is for one side correct?
Strange Pro steel brake kit 33.5 lbs. Just one side as well? or complete kit?
Racecraft Inc. spindles and Strange brake kit 55.1 lbs. Where does this number come from? it is not the sum of the first 2. is it the complete brake kit plus both spindles? or one side of the brakes plus both spindles?
Stock spindles and brakes 97.2 lbs. this has to be just one side right?
Racecraft Inc. vs. Stock 42.1 lbs. I think your selling yourself short with this number. I believe the 55.1 should be a 44.3 maybe?

Also, I see your kit uses 3rd gen brakes and PA uses 1st gen brakes, which gen brake kit is lighter?

 

Yes the PA spindles were 6.5lb as claimed. The hole kit with lines was $1150 very worth it.

 

I have a 95 and just cut my stock spindles. Got the left one down to 11.02 and the right down to 10.94, they were 14.85 and 14.63 respectively. These spindles now look just about how the LS cars look...if you removed their two caliper mounting tabs. Now the weight of the Strange(4th gen) brakes are 18.78 a side, that is for hub and all. My total spindle and brake weight with hubs and all is 59.52.

 

Good Info.

 

The spindle weighs 10.8lbs each, a pair weighs 21.6 lbs the Strange brake kit for both sides weighs 33.5 lbs both the first gen and 3rd gen brake kits weighs the same 33.5 lbs 4th gen kit weighs 37.56 lbs. 21.6 + 33.5 = 55.1 lbs this is what the Racecraft Inc. parts weigh. The same stock parts weigh 97.2 lbs a weight savings of 42.1 lbs. So the same swap using Pa spindles would net 50.7 lbs. another 8.6 lbs. Again the current Racecraft Inc. spindle is a factory replacement spindle which is as strong or stronger than the stock spindle. Racecraft Inc. will have a drag only spindle that will be in the 6.5 lbs. range or lower in the next few weeks. You have to look at your application and decide which type of spindle you need stock replacement or fly weight? Just a few more numbers for consideration:

Stock K-member 47.4 lbs
Racecraft Inc. 15.6, LT1 18.3, LS1 20.2 lbs.
Stock lower arms 15.6 lbs.
Racecraft Inc. 8.4 lbs.
Stock upper arm 5.3 lbs.
Racecraft Inc. upper arm 4.2

Weight savings here is 40.1 bs.

So if you go with a Pinto rack and some aluminum shocks you will probalbly see 100-115 lbs off the front of your car with this swap. We are doing a car in the shop right now and I will post more numbers as I get them. If there are any other question I can answer let me know. BTW The Racecraft spindle mount spindle will accept the Strange single piston brake kit which weighs 15.5 lbs. So that set up will weigh 28.7 lbs in a few weeks, 68.5 lbs. less than stock.
