Fitting a front strut brace and a hardtop made a huge difference to ride characteristics of my cabby.
Made it feel a lot firmer and settled on the road and less wobbly/twisty/noisy with the hardtop.
Made the steering and the front end feel a lot better planted and a lot stiffer with the front strut brace.
I remember before having either of them fitted, when giving the car some welly on a slightly uneven road with even the slightest of bends, the car felt unstable.
With a good suspension set-up, I can imagine an even better ride performance.
But yes, it will make a noticeable difference.
Mine looks like so, but has H&R branding instead of RPM branding, same shape/design though:

If its hinged the struts can move one way or the other and the distance between them will stay the same.

As the hinge will just pivot, if its welded then it can't pivot so will stop this movment.

Hinged ones are okay as long as the hinge bolts can be done up good and tight. To be fair, modern shells are so stiff you don't really need one. I've never noticed a difference on a track day with or without one fitted. I have a one piece Ultra Racing one that does the job.

They probably said the e30 was a stiff shell when they were new before they got to 25 years old and got rusty!
The strut brace on Oz's old tech 1 sport was structural years ago!!! It had to stay on when he had it welded to keep the strut towers in place. He took it off for some reason and i remember it took about 2 hours to get it back on with a jack on the subframe and a 4 foot pry bar to get it back on.
To be fair i've got the underbody X brace on my e36 touring as they flex especially the coupes/rag tops

Pete will reiterate the story but back in 2002(!) when I bought the white C1 2.3, the left had inner wing was so rotten it detached from the bulkhead. So back at Pete's massive the inner wing was portapowered back into place, a strut brace fitted and the car driven to Oxford.Simon13 wrote:They probably said the e30 was a stiff shell when they were new before they got to 25 years old and got rusty!

12 years ago and the car still hasn't been completed. The shell was rebuilt and finally painted in 2007.......
Still, you can't rush leather.

This is true when the sparco brace is fitted correctly with all three holes attached at each side.appletree wrote:If its hinged the struts can move one way or the other and the distance between them will stay the same.

Most just fit them with the top mount nuts, to do it properly would require drilling holes and adding spacers, have yet to see anyone do this!

if it's got t*ts or wheels it's bound to be trouble...............prove me wrong.

I fitted an RPM one to my old 318is , made a hell of a difference you instantly feel and notice, particularly at times like... Comming off a roundabout on to a motorway slip road where you give it some with more weight to one frint corner , it made the car feel solid/rigid/awsome
Need to get one for my tech 1 , ideally want a chrome twin tube hartge but not seen any for sale for ages, the sparco twin tube are £250 odd I feel a bit steep compared to the Rock solid £70 rpm , might get the rpm and powder coat it the same as the rocker and inlet manifold
Glad it was pointed out the White dynamic racing ones are no good as I was concidering trying
Any other options ?

just seen one on ebay, ride height is about -40mm so could catch.zaust wrote:steve_k wrote:anybody know if you can get a underbody X brace for an e30??
Again ultra racing do one for the e30, however the thing will catch on a small pebble as it sits so low down. That's assuming you have standard ride height.
still tempted though.

If you want something that works rather than something shiny, the fixed Sparco is the boy.
I would not be bothered about a chassis brace as the front crossmember does a pretty good job of keeping everything tied together down below.

the current price of the twin tube sparco brace is beyond the joke, £250 for it??
i paid £180 for the front one & a rear one over 8yr's ago, thats some price hike,
pete, just trying to find over ways of strengthening the chassis without going for a cage, as the car will be used for road & track.

Rear ones don't do anything, the "Stress's" go through the rear axle carrier mounts.steve_k wrote:

Pete don't care about colour, He would shag a rainbow if he could find the end of it....

The twin tube Sparco / Hartge brace is decent but pricey and shiny.
Unless you have rear coilovers, a rear brace is not necessary as there is very little load going through the rear towers and any slight movement will not affect the geometry, unlike the front .

pete, keith. i fitted a rear one as at the time i was running coilovers on the rear so had it to spread the load/stress.
