Spohn tubular lower A-Arms with coil spring mounts

Hello Everyone...

Ive been reading many posts in regards to the Spohn front lower A-Arms. Most posts are very dated with negative opinions. I'm looking into options with replacing my front A-Arms and wondering if anyone has installed the A-Arms currently being offered by Spohn on their website. They appear to be an improved/updated version. They are listed as SKU #782-F and currently on sale this week.

Any feedback would greatly be appreciated. I'm installing them on a stock 1989 Pontiac firebird formula 350.

Cheers.

I don't know anyone with the new style ones yet. However, UMI sells a great set of a arms that fit great and they are also on sale this week.

Thanks Phil! And correct, we have been making that new style for quite sometime now and have a lot of great feedback. We have punished them with both street miles and lots of autocross and road course. They are also on sale

Please let me know if you have any questions. Happy Thanksgiving!

Re: Spohn tubular lower A-Arms with coil spring mounts

I have them. They are well built. BUT they have this stupid inner spring ring that holds the spring that really limits springs you can use. You have to cut them out, to really use them. They also lower your car a bit with oem ws6 springs. My tires rub too. I have new tires so maybe that is the problem. Overall go UMI. Wish I did.

Re: Spohn tubular lower A-Arms with coil spring mounts

Thanks for the feedback. The YouTube video online looks great but I'm going pass on buying them. Seems like there are few dated posts with the same issues you stated. I have Eibach coils and don't want to risk fitment issues and the car being too low.

Re: Spohn tubular lower A-Arms with coil spring mounts

Ya they are not bad. But all of the parts are weird. They make a really cool torque arm but the DS loop sits low and has to be cut off and welded higher. Buy them cheap and used.

I have spohn tubular control arms with bmr springs. Didn't have to change anything to get everything lined up.

Looks awesome, did you find that you car was sitting lower after installation at all? Thanks

Re: Spohn tubular lower A-Arms with coil spring mounts

I used the moog OEM Relacement springs. They didn't fit with the rings.

Re: Spohn tubular lower A-Arms with coil spring mounts

I did the drop on stages. I first did the lowering springs from BMR. Then added the tubular control arms. I would say that the ones from spohn did lower the car slightly more. Almost a half inch more from my eye. Not inch and a half. It's inch and a quarter drop springs. Stock ride height
1.5" drop springs from BMR with tubular control arms from spohn front and rear.

Re: Spohn tubular lower A-Arms with coil spring mounts

Call them by phone and they are having a clearance on the a arms from BMR for 300ish. Saved myself money by luck. This was about 2 weeks ago. Hopefully it helps.

Re: Spohn tubular lower A-Arms with coil spring mounts

Checkout the recent post i made about a drop issue though. May have to use a differeny set of front springs to even out the stance of the car. Front did drop an inch more in front:/

Re: Spohn tubular lower A-Arms with coil spring mounts

Years ago when we designed the UMI arms we had Eibach's we were trying. Eibach using a slightly larger wire that still works just fine in stock but doesn't always work with aftermarket arms. They will fit with the UMI lower a-arms.
