MK Indy R Chassis
Breaker - 18/5/09 at 10:24 PM

As I am in the early phase of welding my own "Chris Gibbs book" chassis; and reading now about the new and improved MK Indy R chassis I was wondering if there is a big difference in handling the car ? And will I notice
this in 95% road use?

And regarding the MK body kit: will this fit the "Chris Gibbs" chassis ?

Having seen the R Chassis on the Track - I can verify that it is infinately better than the standard unmodified Indy.

Because the Chassis is better geometrically, whatever engine you have installed is able to get power down (mid-corner) much earlier without getting all out of shape... consequently it is much quicker around a track.

On a typical (CRAP) road, I doubt you would honestly feel that much difference.

There is a big difference on the road. The Indy R is so stable and secure when hammering down bumpy roads partly because there is no bump steer. Paul Fisher and Mad Gaz have driven many miles on the road so they might be able to explain further

A big difference I can spot immediately between the 2 chassis are the front coil-overs. Won't the coil-overs on the MK R chassis become very hot behind the radiator ?

Isn't that the case with any 'seven' with inboard shocks?

If you're worried about damping or the lack of due to oil viscosity then it is a case of choosing the right damper oil in the first place. The temperature should be reasonably constant (ambient variation predominately) if a little high?!

A valid observation though IMHO

With the "Chris Gibbs" chassis you should cut the driving axles by 10mm or lengthen the rear wishbones by 10mm.

Is this problem sorted with the MK R chassis, so no more cutting of axles required ?

Why are you comparing the MK Indy R to the Chris Gibbs chassis???

As I have "the book" from C. Gibbs and an AC/DC Tig welder (+followed TIG welding lessons). I'm comparing the pro's and con's between the MK (newer chassis and suspension, but I would have to buy the chassis) and C. Gibbs (older chassis but I can weld this myself)

Or can't the 2 chassis be compared ?

The Indy R was designed and the first one built before the Chris Gibbs chassis drawings were complete. The Indy R and Haynes Roaster are completely different cars and differ in every aspect. The only common parts are the sierra donor parts

MK's have never had problems with drive shaft lengths

By the way, a member of this forum, 'Raspoet' is from Belgium and collected his LHD Indy R kit last week

I know you are way closer than I am, but not being in the UK will be making things a bit more difficult with building. I would seriously consider the pre-made chassis. You can always weld on things like mounting tabs for the nosecone and a few other things, if you really want to weld.

Does someone has an idea of the toe-in value of the rear suspension?
Rear camber is adjustable but the toe-in isn't,no ?

You can have the Indy R chassis fully rose jointed if you wish,this then allows full adjustment of the front and rear suspension.
