Help with BMR choices

[Furiosa GT]

My new car has more wheel gap in the front than rear and I hate that. Thinking about doing the following BMR upgrades.

Tca048
CB005
BK081
SP076

I am looking for a stock ride quality and no added nvh with this car while improving traction and getting rid of some wheel gap. Also need to make sure the front wheel gap doesnt exceed the rear. What other parts do I need like new bump stops? Do I need new shocks/struts? Handling isn't a concern. Comfortable ride and good strait line traction are. Car is a daily right now and will see the dragstrip maybe 6 times a year at most for just some fun test n tune.
Hopefully BMR will chime in. Tried svtperformance with no luck. Maybe someone else with the same goals will see this in the future.

SP763 springs are what you'll want. It'll even it out and maintain ride quality. I would upgrade dampers if you don't have a Performance pack. At least go with PP dampers, if not the Ford Performance Track or Steeda fixed dampers.

The other things to improve straight line grip have at least mild NVH effects. The CB005 is the best for improvement / NVH. It will add a little bit more noise from bumps but not general road noise or vibration. Most can handle that but it's subjective. The BK081 will add more than you'd want given your goals. The TCA048 adds no NVH so go for it, although the straight line gains are minimal.

I meant SP763. Thanks for the correction. So it's best to go with new shocks/struts huh? Yeah it's a non PP car. So looks like maybe just the CB005? When I track I plan to run a 305/45R17 MT ET street. It might be at least a year until I can get a Whipple so you guys think the CB005, G force axles, SP763 springs PP shocks, and the 17" drag radials would be enough to contain 500RWHP from bolt ons? In both wheel hop and getting all the power down? Also having a minimal effect on ride quality. Thanks for the input

Generally, yes.

 

[Furiosa GT]

Generally, yes.

I would also like to point out that I don't want a jarring ride when it hits certain imperfections in the road. My 13 GT kinda did this and i hated it. Live in Oklahoma(3rd worst roads in the US last time I checked) I know ride quality generally is traded for looks and performance it's just I would prefer it be minimal. Thanks

For the S197, a big part of that was the OE rear shock valving (which I found harsh in my '08, and I actually prefer a firm ride over a soft one). I think there was also some contribution from the OE rear suspension's side-view geometry.

The S550 having gone to IRS should have allowed more comfortable (rear) shock valving for any given performance level, and I think any S197 side view geometry issue would have gone away completely.


As a side thought, make sure that you're not blaming 'wheel gap' for optical illusions that can happen when the front and rear tires are not the same distance inboard of the sheetmetal or when wheelwell openings are not the same shape. Look also at the overall body rake (body bottom and beltline), and make sure before playing games with different amounts of lowering front vs rear that you won't mind having a little more body rake. Headlight aim would be affected as well (lower/less distance).

What I have suggested will have very minimal ride impact in a negative way. You'd have to go quite a bit stiffer to see jarring.

I'm going to suggest the BMR drag springs since you intend on taking it to the strip. And get some ford performance track shocks and CB005, maybe the TCA048 too. I wouldn't add anything else because it will just make the ride harsher which you don't want. Suspension is a slippery slope once you start modding it. Suspensions mods are largely subjective and it depends person to person what NVH level is acceptable.

IMO the CB005 does add NVH and does make the ride more jarring at times (others may vehemently disagree with me). But really the CB005 is a must for our cars because the normal cradle movement is just laughable. But it adds about the least NVH of the parts you listed and really I think it's fine for 95% of people.

I'd stay away from the RLCA bearing based on your desire to limit NVH. I added mine much later after other stiffening suspensions mods, and it does add significant NVH. Good NVH IMO which is why I like, but if I had to guess I don't think you would like it. This is a serious mod and not really for the faint of heart or the very NVH-conscious person.

Also, as you add more suspension mods, the other deficiencies in the ride and performance become more noticable and it becomes a slippery slope. So if you don't want to get in that far (and sounds like you don't) just stick to the more basic mods and leave it alone. That would be my advice.

Thanks for the input.

Anyone have recommendations for other parts that are needed at the same time? Like different bump stops and strut mounts? I know with my S197 car I needed that stuff. Total noob with this IRS car though.

I'd cut your bumpstops per BMR specifications. Alignment specs same thing, use BMR's recommendations. You don't really need anything else. Camber bolts or camber plates would make it easier to adjust the front camber as it is not adjustable from the factory other than slotting the struts. The Ford Performance struts use a strut mount with a higher durometer bushing than stock if I'm not mistaken. The Ford Performance track struts and shocks will improve your handling and your ride. They are stiffer but have plenty of compliance for a good ride. Should reduce some of the "bounce" because of the higher damping. These cars stock all benefit from some higher damping IMO.

 

[Furiosa GT]

What about a rear shock mount like the Steeda? I keep seeing that pop up in threads. Would I need that?

Not a need IMO. But it can be a benefit. One of the mods that can actually make the ride better as opposed to worse.

After seeing the difference between the stock rear shock mounts and the steeda rear shock mounts, I have no doubt in my mind that the steeda are FAR superior and much stronger than stock. Wait til Black Friday and you can get them at a really good price.

 

[Furiosa GT]

In case I go with stock PP shocks would those rear mounts be okay to use with them? No added NVH? Is the ride improved by it being less bouncy or what would be a good reason to get them with those shocks.
Thanks for the help

Yes they would and for PP shocks I'd highly recommend it. Less bouncy by quite a bit, more supple.
