Just try to put front AP conversion kits to my S4s, but clearance between caliper and wheel is not enough. So, have to put 2mm spacer. Does anyone know any side effect of wider front wheelbase by 4mm? Dr.Hess might know it, pls advise.

Thanks Karlfranz, agree with you Spacers are to be used as the last resort. I'm really curious what is the real side effect of increase the positive offset of wheel. I just remember I have a book which I bought in 1984 when I studied in the USA. This book is "HOW TO MAKE YOUR CAR HANDLE" written by Fred Puhn, 1st printed in
1976, 2nd in 1981. He said "Adding positive offset to wheels can make a car corner faster because the wider track reduces wight transfer. However, there are som side effects. On the front of the car, increased positive offset increses the distance between the steering pivots and the center of the tire. This makes the car steer harder. It also increases the loads on the steering system which increases the steering-linkage deflection, and this may require extra toe-in to compensate. All these things are undesirable, so if possible keep the front offset near stock." He also said "if necessay go ahead with small changes in offset and don't worry about bearings. It only becomes an intolerable problem with a large change in wheel offset, say more than 2 inches." He also mention if spacers have to be used special attention must be paid to the lug nuts and spacer must make full contact with wheel. So I might try positive offset for a while, let see the result. BTW if you want copy of this book, give me your address I will send a copy to you airmail from THAILAND to you at no cost. I learn a lot form your website. I read every line before I own my 1st esprit. My email is chalermsak.sugar@inet.co.th

Yes, Karlfranz, all V8 styles will fit. But it will cost me twice of AP kit. Finally I end up with spacer 5 mm from
BRABUS (Benz mod parts), made from good quality aluminium, 2 mm still too close. I will take it for a test run next week (still in garage for some engine works). If thing getting worse, my last resort is V8 wheels.
And for Brian, my 2 mm spacer is custom made from stainless steel, by my friend's machined shop, aluminium is too thin. It would be fragile. If you really want it, give me your address, I'll send it to you (send not sell). No cost, just for friend, don't worry. This is a good thing to be member in this forum.

Thanks Rob.e, but I live in Bangkok THAILAND. And the latest Esprit import to Thailand is S4S.
