I had mine bored all the way through.

The front SE hub spigot is ~26mm tall, measured from the hub or the back of the wheel hub.

I put OZ Novas on my '89, non eagle chassis and found that it increases the kickback and wandering on bad roads. But they do look GOOD. Since I have a portable laser aligner, I played with the toe settings but didn't find a setting that helped. Now the SE wheels are back on the '89, the Novas are now spares for my 2003 V8, and I am happy. Just thought I'd mention that you might not be happy with the results, although it might be strictly dependant on the condition of your local roads. The roads in my area are a bit worn out...
Cheers.

Gixxer, Is it possible that the problem was in the tread pattern doing the tracking on the poor roads. I have had some tires the just follow every little wave. Even on new poorly paved roads. Than on concrete they were great, just a thought.

2005 Elise Starlight Black
1991 Elan Monaco White
1973 Triumph Stag, second owner.
1975 XJ12C Jaguar pillarless coupe.
1960 Daimler Limo, drives great look like hell, project in the works.

I can't measure that now. I do know that it is at least 0.83" (21mm) from measurements that I have done in my brake project.

I understand your point, and my experience is the same.
My tires are Goodyear F1 GS D3s.
No problem with these same rims/tires on my 2003 tho.
All the bushes, ball joints and steering rack are new on the '89. So its either unfavorable suspension geometry (the extra 5 or 6mm of scrub radius from the Novas), or the tires.
Since I've heard NOTHING from anywhere about peoples actual driving experience with this combo, I'm in a bit of a quandry about what brand tires will actually work- if any, to my satisfaction at least.
I think when you have a non-power steering car, the skinnier tires have the potential to actually drive better in any case, even tho the car looks a a bit dated. Awww, it doesn't look too bad....

I have the V8 AWI wheels on my 89SE.





I also went for more aggressive alignment settings http://vulcangrey.lotuscolorado.com/gallery/main.php/d/8157-1/BIG-O_alignment.JPG

You can see I went with ~0.1 deg toe-OUT from the V8, rather than the toe-IN of the SE. In my opinion, this gives much less understeer, while being easily drivable on the street, track, or mountain roads.

The only place my car wanders in in deep ruts on the highway... And it is a handful in the rain in those ruts.

I had Pirelli Pzero Rossos (235/40-17 & 285/35-18) and they drove and rode fine until they fell apart due to a manufacturing defect. Now I have Good Year Eagle F1 GS-D3, and those are very smooth, good handling.

Thanks for the info Vulcan Grey, your car looks terrific! I tried a tick of toeout on the '89 but all it did was get more squirrely under braking. Pre-eagle chassis don't understeer much, at least mine doesn't.
Did I tell you our roads are worn out, and since its Washington-- it rains?
Hahaha!
When my Goodyears wear out, I'm tempted to buy a set of Michelin Pilots for the Novas, then swap them from car to car, if possible.....

When I went to the non-adjustable V8 suspension in my '93.5 with S4 wheels I had many issues with handling. Since I put the V8 AWI wheels on the car it corrected most of them. It could have been an issue with used hard tires on the S4 wheels or a combination of the S4 wheels and V8 suspension, I'm not sure.

Do you need the adjustable bits from the V8 for your custom alignment settings?

Yes, for the V8 wheels you NEED the rear adjustable upper-links to fix the camber. I made my stock upper-links adjustable.

camber correction



end up with these


But you can buy them as well.

For the front, you do not need the adjustable camber. But it is nice. I do not have it and my tire wear is fine in the front.

I also have Spax adjustable suspension set on the stiffest settings in the rear and 2 clicks softer in the front. And I feel like the wheel rate with the V8 wheels works out well, handling is more controlled and the car fees much more stuck to the road.

is there some default distance of rear adj. links for correct setting?

no, there is so much variation in these cars, you will have to have them adjusted to give you the camber you want on your car, with your width and offset of wheels.
