Subject: [Fot] Mk 1 swing spring

Merry Christmas to all. 

Does anyone have any experience with a “swing spring” upgrade for a Mk 1 GT6?  (Non roto-flex)

I am looking for best way to deal with rear camber extremes on my 68 GT6. The rear suspension at completely stock at this time. 

Any ideas on what is best?  I found a part number in the Kastner performance manual but cannot locate retailer. 

How about a camber compensator?  Rear spring is original, so probably due to replace. 

Thanks in advance

Your best bet is a camber compensator.  https://apex2apexmotorsports.com/shop/ols/products/camber-compensator-kit

Sorry Dennis, I don’t have your answer. But I’d like to piggy back on it.

My 14 year old daughter and I are restoring her first car, a ‘63 Herald. We’ll be upgrading to a warmed over Spitfire 1500 drive train and suspension/brakes. Any advice on the rear spring updating to the later camber compensator type? I’m hoping it’s a straight swap with a late Spitfire spring.

Thanks,

As I recall the later style swing spring requires longer axles.

Yes it does. I upgraded a 72 MKV Spitfire to a swing spring set up. Changes
included the axles from a 1500, longer (flex) brake lines (upgraded to
braided while I was there). I also had to make an adapter, IIRC, it was a
3/4" -1" D ring, to extend the parking brake cable. The car already had a
3.89 diff with the 4 stud vs 6 stud spring retainer on top.
My son seems to like the way it handles, the race spit has spoiled me on
street cars and cornering.

 swing springs do not require longer axles, that was a change they made a f=
ew years after the swing spring was added - my race Spit was updated to a s=
wing spring, I also added the compensator back on after an event, car was m=
uch better - ran a compensator on my street Spit with the original early sp=

hey help but you end up with more roll n the rear (they're softer)

On our race Gt6, we have a hybrid system. we have coil over shocks plus a
single transverse leaf mainly to comply with rules that say the
original spring location must remain!!

years ago we tried a swing spring but did not like it on circuit

<div>Herald to GT6 rear spring inquiries ???=C2=A0 Not sure if my experienc=

Spitfire.=C2=A0 A tribute car to the factory endurance cars of &#39;64 and =
&#39;65 built around a GT6 body on a spitfire chassis.=C2=A0 I&#39;m using =
a 4:11 diff with a quaife LSD and for the spring I am using a Composite Spr=
ing from Flex-A-Form out of South Carolina.=C2=A0 This spring is rated at 2=
50 lbs. and is much lighter than the steel units available for our cars.=C2=
=A0=C2=A0</div>

<div><br>
</div>

<div>With all the many options and ideas for set-ups and modifications for =
the rear springs one has to consider the final use for our car.=C2=A0 Mine =
is for autocrossing and the one thing that has helped the most was finally =
switching to this composite spring .=C2=A0 I have about 3 degrees of negati=
ve camber and the car corners flatter in the corners without the notorious =
inside wheel lift and tuck. Handling has much improved in the car, at least=
 for this autocrosser.=C2=A0 I did not op for the camber compensator as gro=
und clearance is reduced as I drive my car on the street occasionally.</div=

<div>Of note, when used the late swing spring on my car I was also using a =
3/4&quot; thick spacer block between the diff and spring to help achieve th=
e 3 degrees negative camber.=C2=A0=C2=A0</div>

<div><br>
</div>

<div>Late Spit Swing Spring, heavy duty Spit spring, modified and de-camber=
ed Spit and GT6 Springs these are the common offerings .=C2=A0 This composi=
te spring is something different as well as some instance of coil over conv=
ersions done by some ingenious owners.</div>
