Im using my car mostly for street and maybe a few track days.
1. Are M030 sways the way to go?
2. Is there a diffrence between US M030 and ROW M030?

Also should I spend the money on a corner balance or is that not necessary?

 

There are lots of good place to buy bars. Here are a few.

I went with MO30s and am happy with that decision. Occasionally you will see 993 Turbo bars available used/new. I believe the front turbo bar is slightly larger diameter than the MO30s. If you want ultimate in adjustability, the RS sways are the way, but tend to be a little pricey. I did get a ridiculously inexpensive quote from Sunset not too long ago.

I did not corner balance my car, however a very good friend recently corner balanced his 993. The difference is noticeable. I think it depends on how you plan to use the car if it is worth the extra $$.

Hope this helps,



Bob-

 

Hey Paul,

Theoretically if you install the suspension as-is it should be close as I had it my car corner balanced when installed it. BTW - I weigh about 175 pounds so if you are a lot heavier or lighter than me, you'll definitely want to consider corner balancing the car.

Enjoy!

Depending on the agressivness of the alignment and the right hight you should be ok with the factory sways. Just get it corner balanced. If you go to the track the difference is noticable.

 

Paul, on my previous mostly-street cab I ended up with a pretty happy setup of Turbo bars front and rear with H&Rs and HDs.

BTW, if anyone wants to sell their Turbo stock bars. please let me know.

 

Very happy with a similar setup to Mikes on a C4S...Turbo front and M030 rear.

 

Louis, how think is M030 rear? If memory serves, Turbo bars are 22/20 or 21/20 F/R, right?

 

I think ROW M030 are 22/20, Turbo are 22/21 -- F/R.

Going by memory here but I think turbo front is 22mm (US and ROW are the same) and ROW M030 rear is 21mm while US M030 is 20mm. 22/21 is a good, neutral setup for a street car and occasional track use. From discussions and research during my decision, consensus seems to be that RS or H&R adjustable sways are overkill unless its primarily a track car.

 

Sounds about right. I remember debating with myself whether I'd want that much on the rear to not bring understeer back. At the end with a fairly benign street alignment and 225/255 tire combo the car became fairly neutral.

Thanks Bill! Great chart....as always.

 

Thanks for the help guys. I might stay with stock unless I can find some used ones.
Do I have to get new bushings, End links or other parts if I upgrade to M030 sways?

 

Best bang for the buck is Turbo bars with the rears drilled for adjustability. In the meantime you can drill your stock ones and dial out some of the understeer.

 

I bought a used rear M030 sway bar last year but haven't even seen a front one for sale. You'll need bushings unless the used bars come with them which they often do.
