I just finished searching through 12 pages of posts about suspension and thought I would still start my own topic since I didn’t find the right answers.

I’m in need of really upgrading my suspension. I have been able to get the car to go a 1.482 60ft so far, but it’s not consistant with the power I’m trying to put down. I know some of my 60ft issue is a combination of running a glide in a 3800lb package with 3.50 gears out back, but I feel I should be able to get it in the low 1.4 range.

Just this last weekend I lost a race from traction issues. The car would hook okay, was only running 1.52 60s, but mostly because I backed the 2 step off a little, but the car would start spinning the tire about 150-200ft out when the power would really come on.

Right now I’m running stock springs front and rear with cheap Lakewood shocks up front and stock gas shocks in back. I have tubular lower control arms I built with the edelbrock uppers and a BMR antiroll bar to boot with a 9”

For the front I’m undecided if I should to the QA1 shocks with Moroso springs or the QA1 shock coil over spring combo. The rear I’m thinking about the Moroso springs as well with the QA1’s.

I’m curious from the guys that are race fanatics like I am, when you did upgrades on your suspension, what springs and shocks did you go with, and did you notice a big improvement?

Thanks,
Corey

I have the moroso springs on the rear of mine and they work good with the HR partnstuff ARB, but I have been told you want equal springs rates on the back with a ARB.

I would stick with a good stiff spring in the rear, you are probably gona have to get a good adjustable shock also. Right now I run a cheap 3way and I am gona see how far they will take me.

I am running moog 5392s from springs and things along with CE 3 ways, in the front. Also you have to make sure your front is very free. Mine was very stiff and then just recently we freed it up and now the front end sits 1 1/2"s lower and we didnt cut the spring at all. I was gona see what changes it did at the track on Friday but as you know the rain came in.

Why not do a complete BMR set up he has been doing it for awhile.

From a spring stand point, I only see that they offer handling packages. Their bar works great and it really helped the car out.

Cory call him he answers the phone I just got trick springs front and back also Ford rear end upper bar relocation kit anti roll bar track links and shocks from him. Still need to put it all in. Sid Colman's relative ?? has BMR set up and it HOOKS he posted pictures on one of my threads
PS Corey I searched Dick Miller Racing and found my thread look for Sid Colmans post I'm sorry I don't know how to link it.

 

[67TurboChevelle]

I saw some of Sids photos in the search I did this afternoon, very impresive leave on his car.

I didn't think about them making a relocating kit for a 9", although my upper bars are really raised up at the rear end housing and it looks like my center intersects around the back of my door. Just a guess though, I haven't ploted the points.

I'll probably move forward next week once I get my thoughts together. I have a new cam shaft coming next week, so I'll have to move pretty quick on this stuff :hurray:

I have the MOOG 5392's also with KONI street adjustables set on full soft on extension(recommended by Ed). I had to trim the springs when I went to alum heads and had to trim them again after leaving the inner fenders out,going with a glass bumper and moving the battery to the trunk but it has still gone 1.349 best in the best air we've had since May,2000ft air and it went 1.388-1.397 last weekend in 3500-4200ft air. I am going to get a new set of springs as soon as I get a new front end weight on the car at Tulsa the end of this month.

I have a Moser 9" Mr Miller says that it was not raised enough and recomended the relocation brackets

Corey,

I have the QA1 DAs and Moroso springs in the front of my Camino. Stock type cargo coils and QA1 DAs in the rear. Moser 12 bolt with Wolfe Racecraft control arm and anti-roll kit. 3822 lbs and on 325/50 DRs has gone 1.37 60 ft so far, lifting front wheels about 6 inches.

When I put the 8" converter in a couple weeks ago I ran 1.36's with my car. Rear is lowered, double adjustable control arms upper and lower, in stock locations.
HRparts'n'stuff rear anti roll bar.
3 way adjustables on front, red ryders on the back.
My 9.5" converter will only run 1.43's.

 

[Dave Kaveshan]

Oh yeah, good point about the right converter. I think mine needs to be tightened up a bit. I will probably go back to a 30" tall tire too.

Brian, 1.36 in 60' is really good. I know you were making a number of changes to the car (front suspension/springs as I recall). How repeatable are the 60' times with the new converter/changes? Thanks.

I believe he actually put grease into all the grease fittings!
Impressive two weeks ago even with not-enough fuel getting to the engine.
Can't wait to see her make full-power passes.

Here's the post from the 2nd outing with the 8" converter......1st time out were 1.39 60ft's.....The following explains most of it.
It was only a borrowed converter and cost me some mph on the big end and what I gained in the 1st half I lost in the 2nd and still ran very similiar et's....Actually a little slower.
I put the old converter back in and 60fts' went back to 1.43/1.44 and mph went back up....ET's actually a little quicker, Last sat. I ran 10.07, 10.07, 10.08,10.06
DA was 2150, 2138, 2200, 1750 respectively. This was with some bigtime head wind. Mph was down to 132.
60fts went back to 1.43's with the 9.5" converter.

Well, no 9's. But I decide to do a few quick susp. changes yesterday before going to the track.....(when I should of been home swapping converters back out)

So, If you recall I had lowered the front of the upper control arm mounts, last year. Which seemed to help but I made a tire size change at the same time......
This spring I changed front springs, lowered the rear some more, etc. etc.

So 1st off, I take out the moroso springs, put back in the moog 6cyl springs I was using last fall. Car now sits about 1.5-2" higher. I get about 5" of front travel. The springs will probably settle a little after a couple days tough.
This I had to do, because the moroso's were just too low.
They were sbc springs though.

I put the rear upper control arms back to stock location. Stuck a degree finder on the lowers, they are at 0*. That is how much the car has been dropped in the rear.

I reset the Hrparts bar with some weight in the drivers seat. 2 BBC heads and a pail of 12 bolt parts. About 200#'s. Still a few short of myself but close enuf

Reset the pinon angle and here we go off to the races.

Now that I have just completely reset the whole susp. Front and rear, I am thinking good god what did I do. But, I was sick of the headers scraping away......not much left of that tube

Oh yea, I drained out the E10 and found some 100% 93 octane, if it even really is.......There are not many stations left that show no ethanol.

Ok enuf rambling

1st pass, DA2455 calculated, no I didn't buy a weather meter. But my last outings were all around 1000DA. 2600ish rpm foot brake

1.368
6.379
105.580
10.124
130.462

2nd pass, tried a mild 3600rpm t-brake launch. Didn't like that.
DA2000
1.438
6.444
106.006
10.182
130.517

3rd pass back to footbraking 2600 rpm or so.
DA1995
1.365
6.352
105.954
10.086
130.753 Son of a......10.086 a 10.09 dial in. and I had a better light. Damnit.
I had him covered and should wacked the brakes but,.....it coulda been that 9 sec pass

Too bad the weather wasn't a little better
But the short times improved. That is a good thing.
It didn't respond well to the brake.
15 psi cold in the Hoosiers.

I talked to Charlie @ ATI friday.
After asking me several questions and I told him about the results of each converter, he says......
Quote:
Your car runs excellent especially for a pump gas engine.....Wow, this thing is making around 750hp.... Based on your numbers, your edge converter is locking up tight and your overpowering the 8" up top.
I think we need to build you a 8" converter that will launch in the 1.3's and lock up on the big end. I assume your looking to squeeze into the nines. I think we can do that with a tight 8" converter. Something like what Bigley is running, Todd's is a little looser than I would like in your car. But your car runs dang good as it is. Just remember no transbrake and no nitrous unless we upgrade the converter but that will add about 7#'s.

So if anything I felt good about the car after talking with him.
If I decide to chase that last tenth with a converter, It will be an ATI.
But for now, I think I will see how the edge works again with the susp. changes.....Maybe the 60ft will still be better with the edge converter too.
That's what I am hoping right now anyway. If not, this test defineately shows that the car likes more converter as far as the first half of the track.
And was a good learning experience. It was a test, and all it cost me was some labor/time. Can't beat that IMO

I have seen my name mentioned in this thread. You are all welcome to call me any time at tech 662-233-2301. No one makes a stronger or more adjustable suspension system than I do and still lighter than aluminum. I can make our kits work. I presently have a customer running 8:02 in the quarter on 10.5" tires. I am sure there are some Chevelles out there doing as well. I will try to educate you but I am not interested in making other companies parts work when they can't.
