Hi
The build is underway, floor oan stripped ready for shortening, at the sametime I am converting my swing axle to IRS and have managed to get some irs arms, so can start installing the brackets using the jigs.
To make it easy to adjust the ride height on the chesil kit I want to try and keep the swing axle torsion bars and cut down the plates to fit the IRS arms.
The IRS arms have 4 bolts a double plates, so can you use single 3 bolt plates with these arms?
Cheers

Yes you can. I'm in the midst of re-doing my irs now- I have short swingaxle torsion bars and am using cut down swingaxle spring plates (they needed to be narrowed, shortened and the bolt slots cut in; oh, and of course I'm drilling a few holes to lighten them a tad more!). Originally I set mine up with Sway a Way adjustable spring plates, but I've widened a pair of 6" Fuchs alloys 1" to the inside (a la '67 911R 7's) so I can fit 205/60's with the 7" wheels under the fenders and the tires hit the adjuster blocks on the spring plates. They are also over 6 1/2 lbs heavier than my cut down swingaxle spring plates (that's reason enough to get rid of them!).
With normal irs torsion bars and spring plates I don't think there's enough room to reset the torsion bars should you ever want/need to so that's why I went with the swingaxle torsion bars and (modified) spring plates. Al
Great thanks!

Yeah, there is....... All you need is 2.75" to pull the torsion bar or end cap out enough to disengage the splines to allow it to rotate. There is at least 4" - 5" of space between the body and the torsion bar end cap/spring plate end to maneuver it out and in (at least there is on my CMC widebody - Maybe a classic body has less clearance but at that location they should be the same.
Thank you Gordon; I didn't think there would be.
@ALB May I ask what widening Fuchs cost?
Just outside Vancouver city proper there's a wheel re-finish/repair shop called Green's Automotive that also widens and narrows wheels to order. It was $250/wheel, but labor here is significantly more than most places stateside, so it may be cheaper to do where you live. It's where Intermeccanica has their wheel widening done (Banzai's rear Fuchs were done the same way). While it was a tad expensive, so far everything fits under the body work and I have 205/60's on the wheels at the moment. I'm a firm believer in running wider rubber on the back if you want the best performance out of any rear engine'd car- look at what Porsche has been putting on the backs of their cars to tame their handling for the last how many years? A while ago I walked up to a newer P car and it had 305's on the back! Ask around at any tire or automotive shop and they'll be able direct you to the nearest place that's good. Hope this helps, @Bill Prout
Thanks Al. Still less than a real pair of 8" Fuchs. I've managed to hoard three sets of 6 and 7's but could never find a deal on two 8's.
I have 6 and 7 in back
Green did my total refinishing did not expand the wheelsFuchs. 16 inch
great job
