Kafer Cup brace, beefing up rear...

Those especially with pan based cars...

How steps do you do to reduce wheel hop and contain power in some of those large TIV and TI engines that are producing in the 150 hp range and above?

Views on solid mounts, straps, and such would be appreciated.

Any conflict in pan based replicas with Kafer type mounts with sub structure?

Thanks in advance

The CSP Torque bar when installed will drastically reduce or eliminate wheel hop. I suggest them for spirited driving or for any engine at or above 150HP, or 140 lb/ft of torque..

Kent,

I plan to fit a kafer brace over the winter and have one sat waiting to install.

Doesn't appear to be any conflict with the rear sub-frame of my Chesil but i'll have a much better idea once i've started the install. Will keep you posted.

Simon,
Check again, If your Speedster is VW pan based and has the rear subframe, the Kafer brace won't fit.
I tried to fit one on my Vintage Speedster. The braces that go from the shock horns to the trans yoke, need to go right through the rear sub frame. (The part that the body, right in front of the firewall,mounts to.)
I've seen a similar brace that looks like it might fit. I forget what name it goes by, but aircooled.net had them on their website last time I checked.

Greg,

The vintage sub-frame must be different to that on the Chesil.
On the Chesil all the structure stays high at the rear of the car except the bar incorporating the rear seatbelt lower mounts which runs parallel and infront of the kafer brace between the shock towers.

See the photos in my file (originally taken when I had to replace a tranny oil seal that failed)

I think it will fit ok

Simon,
Your Speedster must be different than the Vintage setup.

It's a photo of a Vintage Speedster without body. (roller). This photo shows the rear frame that's in the way.

Good luck. Post some pictures of the Kafer when completed.

We braced the bee-Jeezus out my driveline with solid mounts, not the rubber dudes, GB643-thingie and in another few hundred hours I am going to dump the clutch again to see what happens...

At Knotts last year I hadn't finished the bracing and only had the GB643 in place. I cracked the nose cone when I hole-shot a Cobra on Beach Ave...no wheel hop though, just lit both tires and saw the tach scream up to 7000+, hit second and away we went, with yet another signature asphault burn!

Currently, with more bracing as described, all I can say is if you want a 'seat of your pants' driving experience, stiffening up the mounts to support a torquier engine will give it to you...along with a need to see your dentist to replace a loose filling or two!

Tracy Grimm makes a bolt-on brace that the hi-po VW guys swear by.j

Greg,

Wow, thats pretty substantial box section at the back of the Vintage.
My Chesil is similar to the pilgrim shown here, but has more triangulation at the rear plus mounts for rear seat belts.

With such a substantial frame on the Vintage, couldn't you triangulate out to that from the frame horn instead of up to the upper shock mounts (given a suitable shorter adjustable rod)?
