Indy handling
Been on a bit of a quest to improve the handling of my Indy…
Not that it was that bad to start with but you can always do something.
First was fitting a quick rack. I have spun the car twice now and both times I am sure I could have corrected if I had been able to get on the
steering quicker.
Next was the front springs.. With the bike engine the front of the car was about 30mm higher than the rear even with springs at their lowest setting.
So I got a hold of some 7” 300 lb springs – so that’s the ride height sorted.
Next corner weight using the bathroom scale method. 10kg imbalance on the rears 2kg on the fronts.
1.5 deg camber on the fronts and 1 deg on the rears - 0 deg toe in were next set after quite a bit of roundabout testing!!
Now getting a nice progressive oversteer which I can hold with power if required and correct quickly if it starts to get too wild.
I am still going to keep working on this.. a little bit at a time…

Your driving is awesome Andy T. Tis was you who made a man sell his Cosworth 4x4 to fund a bec indy. This is the stuff of legends.
80 Mph four wheel power slides round the Knock o: are something that I will not forget in a hurry.
Thats the fun of bec.
What Hector liked was the ride that your car gave and the on rails round corners feel. Noise was a bonus.
Make it better mmmmmvery hard to do when its so good to start with.

Have you found the quick rack has made a big difference? That's one of the first things I noticed in my Indy - it could definitely do with
quicker steering. I find the thing that limits my cornering speed isn't grip but how quickly I can turn the wheel!

Quick rack - go for it definitely.
Nuff said

No..No..No Pat!
You just have to go along to any sprint or hill climb to see some real driving!
I am always amazed at the way some people can handle a car.. the best always seem to have everything in "balance"
me - I have trouble standing on one leg!
The quick rack does make a good difference but it will make your steering heavier by a small amount. If you have a heavy engine and a small steering
wheel you may find parking in Asda a bit of a chore!

That is information that a lot of us have been looking for, for what seems like years! It's good that you have proved it out too... marvellous!

I don't have a quick rack in the GT1, its personal preference i guess but it makes the car too "twitchy" for my liking, anyone who
saw the car thru the hairpin at Mallory or the chicane at Donnington will realise i find it to be no disadvantage, at speed you need much less
steering input too turn in and the right foot takes the steering off.

A quick rack may be more benefitial on the road than on the track - on the road corners tend to be 90 degree bends with no lead in or lead out and so
you want to go from straight ahead to suddenly turning at 90 degrees and then suddenly straight again. This is what I've found to be a problem
on the road so it's definitely something I'm considering, but I agree, it is down to personal preference.

Got to say that this is a set up for me and what I will be using the car for ie hill climbs, sprints and short tracks ie Knockhill. At high speed it
will get more "twitchy"
