Not for the track they're not.

Mild street driving, sure.

Track, they'll die with the quickness.

So again, i ask you to explain to me how a rollbar stiffens your suspension.


Unless by "stiffens the chassis" you really meant "I made a herp and i derped and said that a rollbar has an effect on my suspension when clearly it stiffens the chassis instead."

Hobo Jonny

It was a silly type-o. In my understanding, the rollbar will effect the way your suspension is setup (spring rates) because it significantly will stiffen your chassis.
From following track threads and other build threads I've seen countless times the suspension (spring rates) needing to be changed because a different rollbar (or mild cage) was added.
I'm new to this but my approach was going to get a rollbar and work on other suspension components first, (stiffining the chassis) before getting coilovers or whatever so i can get the proper spring rates/setup for what i got instead of buying twice.

Please someone with more knowledge correct me if I'm wrong.

Why not just get the proper spring rates the first time?

LOL..
Aright, I'm no expert, this is just how I see it.
In this picture you can see how little there is between the front and rear axles.

I know.. NC.

To me, this is where Miatas and all other convertible have most of their chassis flex.

So, attaching a roll bar like the harddog, etc. does nothing to stiffen the actual problem. It's mounts are completely behind the door openings.

A car with a full cage..

Fills in the open gap, front to back, across the interior, boxing it in..
This will stiffen the chassis, not a roll bar.



Just my 2 cents..

Your only flaw in your reasoning is the assumption the center section of a Miata is the only part that needs help. The front and back are floppy too.

M.Adamovits

Of course. It's a floppy car.


But a roll bar doesn't add to stiffening the chassis a noticeable amount.

Its noticeable. Very noticeable.
Drive 2 cars one with one without back to back you'll be very surprised.
But obviously not nearly as serious as a cage is what I think you meant to say.

My front is kinda floppy but my back end is tight.

I'm running Megan EZ Streets and I love them. I daily my car a lot so I wanted them to be somewhat comfortable. I also autocross and they work out really well. At full soft the ladies are happy and at full stiff I'm happy.

Should I have said at full soft no one's happy?

I have raceland coilovers on my 91. They were on the car when I bought it. They go low and are very comfortable for daily driving and are a decent coilover for $350. However, they are only a good option when you just want to lower your daily I would not recommend them for any track use and I plan to upgrade before I start tracking. I have hit the canyons quite a bit in them and they feel quite sloppy in comparison to other coilovers I have had experience with.

Is that what he told ya?

save up and buy decent coilovers. I ending up with the flyin' miata vmaxx coilovers and love them. they are great for what i paid.
