Next mod / setup advice (suspension)

[dentnshell]

Recently added an ADM LSA conversion to my GPI SS1 cammed 2014

Car has a BMR 1" drop - Rear tires are 305/35/20 Pirelli P Zero's on 10" wheels. The amount of torque on hand is "impressive"
The car is fun to drive but, but you have to drive it! With just the cam. It was a brainless act. With the LSA you had better not hammer down. The car breaks loose way to easy and on shifts seems to have a rear sideways jump.

I am looking at BMR Toe Rods... Trailing arms... and Cradle bushings.
I feel like alot of the problem is I also need the Posi mod... ( I keep bouncing back and forth between the mod, and a ZL1 rear end. I keep thinking the money I spend on the mod could partially offset a used ZL1 Cradle

The car is my wife's daily driver... will likely never see the track or strip.
Also shopping for my next set of tires... I need an all season (Oklahoma) that has a little stick - Besides if the tires grab too much I will need new axles.

Currently the car is alligned at factory spec. I know an alignment will help things alot... but my tire wear is perfect now.

Opinions???

What are doing for Lower Control Arms? As you lower the vehicle, the Camber gets out of whack. Our TCA028's are a different length to correct the Camber. When you do this you will also need Adjustable Toe Rods. Cradle Bushings, I would do our Pro Version Full Polys.

On another note, since this is your wife's car and it seems pretty stout, driver training for her and yourself would make a great Christmas Gift!

Um, I'll have a posi-mod unit for sale here shortly ;o) Done by GPI, I'm going trueTrac so I can run NCM...

Now that the hijack is over ;o), agree with alignment but, trailing arms/bushings, toe rods would be a big help first. Cradle bushings would be next -- I personally like the solids -- I did have the BMR, but felt it moved too much. Upper Control arm bushings would be after that...

I've done them all -- and now found I needed to do the diff bushings after racing at NCM.

Sometimes, its best to save up and do these all at 'once' then, get the alignment.

Have you been talking to my wife??? She wants to take a training course at Hallet (about 50 minutes from us.) I keep putting it off. She has grown into the car we did the cam first... then FI...

Exactly the information I was wanting... Adjustable or Not. I know the 1" drop makes it borderline on needing the adjustable links.

lol. I've been a Racing/Driving Instructor for over 25 Years and I believe in people having the skills to be able to handle situations in their road cars. I know my Training has saved my bacon a few times. 1st thing I did when my son was of driving age, I sent him to two driving schools (Audi & BMW) even though he had raced Karts for 4-5 years.

On the Toe Rods, you are Borderline!

[dentnshell]

Are the stock ZL1 (2013 ) Toe Rods and trailing arms an upgrade over the SS parts?
I have decided to go with a ZL1 Differential and Axles. Didn't know if they other parts would be an upgrade (for the time being) over what I have or not. The price would be minimal compared to adjustable (Future upgrade.)

Thoughts on the ZL1 sway bar?

[1KillerSS]

Honestly until you get proper tires on it, your wasting your money. Get some DR's or smaller wheels.

[wrtowman]

I just had the same upgrade done as you. I also pieced together some suspension bits to the rear and couldnt be happier.

BMR LCA which you dont need since you already have FE4
BMR Toe rods
BMR trailing arms
ZL1 sway and end links(I have this for sale)
DSS 1kHP axles
ZL1 hubs


Everything you need can be had brand new for 1400. Less if you browse the forum.

And of course you need some grip.

Ok - So the ZL1 Diff and axles are in. Also installed the ZL1 Rear Sway.
Solid Subframe mounts are on the way (I wanted to install at different times, just to be able to feel the difference in how the different parts made the car feel.)

Next?? Remember this is a 2014 with FE4
Do I need TCA028? If so BMR's documentation about endlinks "seems" to be confusing and the first note **** may only apply to 2010 and 2011????

Also BMR TCA033 - I am not sure I wouldn't prefer Detroit Speeds DSE-042303 due to the polyurethane bushing vs a spherical bushing

Finally BMR TR003 - due to maintenance I think I would prefer these over the TR004. And for that reason I have concerns about the above trailing arm... I am ignorant about the true maintenance and longevity of the spherical bushing. I am simply going off of the BMR Website information.

So with the 2014 FE4 lowered 1" do I need or are Control arms highly recommended?

Your going to spend a ton of money on suspension parts, I did, and still had issues. Not as bad, but it didn't help any where near as much as a 700 dollar set of drag radials. Just saying....

I would recommend them mainly due to the Camber issue when lowering - some cars can get away with better Camber Bolts

Hoping for a Black Friday sale.
Looking at adjustable toe rods - TR003
Rear Trailing Arms and bushings (Non Adjustable) TCA026

Trying to decide on bolts vs control arms - TCA028

I have been looking at the article that superchevy did on a 2012 ZL1 and noticed they did not do the adjustable trailing arm, even with the new control arms...

Thoughts??? I simply don't want to spend money on adjustability - If I don't need to adjust.
