Mono ball front strut mounts

[JOHN21BLACK]

Are solid strut mounts to hard for Street use? Should I go with ER rubber upper strut mounts.

[Matthew Barnes]

Would have said mono's on the front struts are more about precision geometry than ride comfort. In my experience, the shock set-up, ride height and torsion bars will have more effect on the ride quality, than swapping out traditional donut strut mounts for monoballs.

[JOHN21BLACK]

I'm running Bilstein sports on all four. 23/31 Saunders solid torsion bars and Euro height.

I had a slightly softer set up than you are running and when I added them I did not notice a change in harshness.....it was pretty firm already.

[JOHN21BLACK]

Good to know. Thanks

Are you considering only Elephant Racing products or are you also looking at Rebel Racing? I am going through a similar evaluation process - looking at RSR Semi-solids as well - please let me know what you decide.

I went with ER rubber. I think Craig_D's suspension thread discussed this. IIRC, he tried the monoball and they were too harsh for street use. Harshness is subjective.

[Bergo]

I run the weltmeister monoball camber plates up front, bilstein sports, 19mm raised struts, it's not too harsh for street driving for me.

[JOHN21BLACK]

If I go with solid monoball. I will use Rebel Racing. If i go with Rubber. It will be ER. Trying to get some more advise from fellow pelicans. I dont mind a hard ride for street. Not a daily driver. Going to be a canyon carver and some AX.

JMHO,

Street cars get rubber, race cars get monoballs.

I have the ER monoballs. Not more harsh ride, but my car has no rubber components otherwise anyway, so it was already harsh. Certainly a little more high frequency road vibration but after a few days that feels normal.
If I would do it again, it would not get the monoballs only, but rather the adjustable camber plates which itself have monoballs, at least the ER ones.

On my '88 I started from the original stock rubber strut mounts as well as the entire front suspension. Installed Rebel A-arm hard bushings, 22mm torsion bars, turbo tie-rods, custom valved Bilstein sports for the 22's and capped it off with Elephant strut mount camber plates w/monoball built in.

Of course the TBs made the ride stiffer but the combination of all elements have made the suspension way smoother and LESS jolting. You can actually feel the suspension "move" and react to bumps instead of the jolt I used to get. I agree with Horst that on high frequency road surfaces there prob is some vibration that rubber might isolate. According to Elephant and my local P-car race shop, the mono-ball camber plates allow you to get a little more negative camber then the stock rubber ones. You can always sell them for prob 70% of value if you feel like they make a negative impact.

Now the Rebel rear polyurethane engine mounts I just installed made a very noticeable difference in high frequency vibration in the rear, not bad but noticeable.

[Elombard]

/\ that is exactly right. I had the Poly Bronze bushings, turbo tie rods, T bars, Konis and monoball strut tops. Once I got the alignment and corner weight right the suspension was so supple and you could feel it moving and what it was doing. It was harsh in some situations.

I'm re-doing my suspension this winter, and just tore off the front suspension. I have ER mono balls for the front I plan on installing as well as planning Rebel racing bushings front and rear along with ER rear mono balls. Hoping its not too harsh! Guess I'll have to report back in the spring! But like others said.. it's subjective. Hopefully I'll be on the side of enjoyment rather than annoyance.

I don't think it's really worth fretting that hard over. I run the eBay spherical plates, and had one of the cheapie bearings die on me pretty quickly. I swapped the OE ones back in while I repaired them, and didn't notice much of a ride or performance difference, even after swapping back to back, in competition autocross use. I for sure can get more camber with the aftermarket bits, but that's it.

For a street car, on street tires, I wouldn't even bother touching the factory stuff unless it's falling apart. The OE part is durable and well designed, and there's not all that much compliance in that area. Full race car on R-comps hunting down a final 1/10th of a second? Then yes, maybe worth it. Bigger fish to fry up front is hunting down and eliminating as much bind as possible in the a-arms and swaybar.

If you MUST buy fancy monoballs, I doubt you'll regret that either. They won't suddenly transform your car in any way whatsoever, neither good nor bad. Small difference.

IMHO, YMMV, and all that jazz.

[Elombard]

Yeah I wonder if old rubber a arm bushings combined with the stock front sway bar set up are really messing up the ride on a lot of cars because of binding and a compromise design.

[impactbumper]

I just did Konis all around, polybronze ER and ER rubber top mounts.

I didn't mention it in my post but I did my entire rear end in addition to the front. 30mm TBs, Rebel rear spring plate bushings, swaybar bushings, re-valved Bilsteins. But.. I went with Elephant rubber "sport" hardness trailing arm bushings instead of mono-balls. I have no idea if mono-balls in the rear would of been to harsh but considering whats involved installing and god forbid removing, I didn't want to take the chance. Just a thought..

Sage advise from someone who's been there, done that, many, many times.
