Pure Stock Suspension
 

Hello there,

I was just curious as to what suspension adjustments are acceptable for IHRA Pure Stock rules, just building a car and just want to be 100% certain

Re: Pure Stock Suspension
 

What kind of car ?

My 95 Mustang Pure Stocker has the Mega Bite Jr. lowers and it really helps plant the tires.
I still use the factory uppers with stock coil springs and one coil removed.
I also still have the factory sway bar.

I believe the rule says they have to be bolt on arms, ( no welding on the rear housing)
However, the lower control arm cannot be adjustable in length ( no heim ends)

Adjustable shocks are legal.
No coil over shocks allowed.

Here is the link to IHRA's site for the on line rulebook.

Re: Pure Stock Suspension
 

I know that Caltrac's are not legal. I sent an email to Mike Baker questioning that and he responded they are not legal at this time.

What car and body are you considering?

I was kind of confused with this as well. Was toying with the idea of building a Pure Stocker, and wasn't sure how restricted the suspension actually is.

The rulebook states:

"SUSPENSION: Must be OEM per horsepower claimed. Any stock type shocks permitted. No other suspension changes or additions permitted."

I almost read that as saying you can change the shocks but no other changes are permitted. Obviously can't add things, but can't swap either? So you can't change control arms to aftermarket even if they bolt in the stock location and are stock style? Can't box/reinforce uppers and lowers on a GM A/B/G body?

Re: Pure Stock Suspension
 

YES .. HD Bolt On rear control arms replacement is fine.
Boxing is fine since it makes the stock arms stronger.
Hardened Bushings replacement is fine.
Does not change the geometry.

So long as it does not change the suspension design.
Which most don't. Safety first is good..!


My car uses 3/4" longer control arms to fit larger slicks.

Thanks guys,

It's a 2002 Camaro SS, was just looking at points of improvement on the suspension, and just trying to figure it out

Re: Pure Stock Suspension
 

Anything that is Bolt On..!

Reinforced Stock Suspension pieces making the car stiffer and safer.
Better control arms, or using better replacement bushings.
Front Shock that behaves like a 90/10 shock.

Good set of gears, sticky tires and that is about it !

My son is working on his 2002 Camaro and this is what I have be told that on the rear you what a good anti roll bar on the rear or the largest anti roll bar. That year of car you could get as a cop option with a larger bar. I don't know how well the stock toque arm will hold up, they do make a better bushing for the front mount. I looked at some pics of some that have failed and it not pretty. Tom

Thanks Guys,

I'm just asking because I have these parts , see attachments, from another car, and was wondering if they would be ok, as they are needed on the car I want to make into a Pure Stocker. They are all bolt on type. If not, I would then have to enter a standard stock class correct? As well I have frame connectors on it. And front bolt in suspension where I couldn't find an link

Re: Pure Stock Suspension
 

These are just fine.
They bolt on and do exactly what the originals do.
Except more robust..!

Re: Pure Stock Suspension
 

Lower control arm relocation brackets are legal in Pure Stock?

Re: Pure Stock Suspension
 

Yes....
Dick Miller sells them for most 4 link GM cars.
Has others for Ford and Chrysler.
They are bolt on and no welding.
Been this way for decades.

I am considered a set Upper Control Arm brackets.
Which will change the angle of the Upper Control Arm on my b-body.

Re: Pure Stock Suspension
 

FWIW.
Very few rules are different between Stock and Pure Stock.
A or B Pure Stock may need similar safety equipment from M Stock and above.
Such as a Roll Bar and Safety Harness.
Pure Stock are the older 70s 80s Stocker rules.
Safety still rules!

Re: Pure Stock Suspension
 

YES good Point Gbur;
No, on lower Rib !!

To settle it ...
Email Mike Baker at MichaelBaker@LiveNation.com
This is his latest email address.

Then let us know what he said.

Re: Pure Stock Suspension
 

i can't see where that type of suspension would help this car especially if it will be an automatic. If you have good bushings in the stock control arms, that is all you need.
Put some new shocks on and some good slicks or drag radials and it will hook anywhere you race.
By changing all of that, you are getting away from the intention of the current pure stock.

If pure stock is meant to be an entry level class, you certainly don't need to spend $800 on those parts. They look to be too adjustable for the way the rule book reads anyway.

Re: Pure Stock Suspension
 

Regular Stock and Pure Stock rules are near identical.
We are allowed a 3/4 inch change forward or rearward.
In my case to be able to add 30 inch tall slicks without interference.
As for good bushings...oh yes.
Stock ones with a bunch of miles on them will get the crap beat out of them drag racing.

Again chassis upgrade parts are more for safety and reliability.

Re: Pure Stock Suspension
 

I believe the 3/4'' +/- is not for relocation but is tolerance of wheel base.
On my car have urethane bushings and boxed stock control arms.

Re: Pure Stock Suspension
 

You are correct.
Use that tolerance for the B-Body Chevy's.
Have Dick Miller Bolt on stuff.
My stock arms and bushings were all beaten up after 200k of driving and many runs on the Strip.

Re: Pure Stock Suspension
 

How about adjustable pinion snubbers?

Re: Pure Stock Suspension
 

YEAH you can do that!
Once you establish best height you will not move it.

I used glue and pieces of wood on my 1969 Impala.
Make sure you have a full inch of travel.
