348: best spacers setup / tried them all

No one has them with the car they are like $6K. But, they are available on line of you search a bit is all. Run some searches some inks were posted recently. Can find them on ebay on cd and hard copy reprint as well.

Jack up the front, grab the wheel o other side of the steering wheel and shake, confirm the outer rack bushing is not shot, It will be VERY obvious if it is, they all are eventually, usually like 15 years ago and people drive with wonky steering never understanding why. And lube your shift cables and shift box. 25 years and it has never been done guaranteed. Post 16.

Good luck.

 

The 25 mm spacers (Type 2) are bolted onto the wheel hub with the short bolts provided. The spacers have another 5 threaded holes in them to which you bolt the wheels. In this way, since the spacers practically bring the wheel hub face out, you don't need longer bolts. On the Hill Engineering's (HE) 25 mm Type 2 spacers, the said new 5 threaded holes are inside steel inserts (much better) and not threaded directly into the aluminium body of the spacer like the ones on Ebay.

HE also have Type 1 25 mm spacers which are mounted in the usual way (no new threaded holes in them) and these come with very long bolts (+25 mm). I wouldn't go for these as, in my opinion, so long bolts may not provide strong and rigid clamping of the wheel. I am using HE 25 mm Type 2 and also like the fact that the spacers always stay bolted to the wheel hub so removing and fitting the wheel is easy, same as if there are no spacers.

After I removed the front 15 mm spacers, my 348 does not look "funny" at all to me, just "normal". The look is not at all something that one would notice. The following are the choices for you:

1. Better looks and moderate improvement of the high speed stability - 25 mm rear & 15 mm front but risk of "unfolding" the wheel arches from time to time; you can consider rolling the wheel arches somewhat to reduce this risk.

2. Best improvement of the high speed stability - only 25 mm spacers at the back.

 

Hi guys!, yesterday I received the spacers for my 348. The ones for the rear are 25mm and bolts were included. I also bot 10mm spacers for the front but the bolts are not included, can you confirm if the following bolts (65mm) are the ones I would need for the front?.

thanks!

 

Or maybe needs to be with cone form?

If you look at the original bolts, you will see that they are cone type. 65 mm should be the correct length (55 mm original +10 mm for spacers, dimension L2 on the pic below). However, I wouldn't go with CKS's universal fully threaded wheel bolts as they are not as strong as the original part threaded ones.

very much what is said here +1

But the right bolts for the application.

 

Thanks a lot. If I am not wrong, I read that for the rear with 25mm spacers I can use the OEM bolts, is that right?. The bolts that come with the spacers 25mm spacers have a different look and would like to match them with the OEM or the ones I bought from Hill Engineering (look OEM).

 

Wheel studs are the easiest solution I run them on mine Image Unavailable, Please Login

What type of 25 mm spacers you bought Type 1 or Type 2? How long are the bolts you got with the 25 mm spacers?

 

They are type 2. The bolts look kind of short about 30mm.

 

With the short bolts provided, you bolt the 25 mm spacer to the hub and this assembly stays always bolted there. The wheel is then bolted to the 25 mm spacer with the original wheel bolts.

For the front 10 mm spacers, you cannot use the original wheel bolts but need to buy longer bolts, same as the original ones but 10 mm longer; you can get them from HE, select 65 mm length after verifying that your original wheel bolts are 55 mm long (https://www.hillengineering.co.uk/wheel-related/wheel-bolts/bolts-by-length/wbbl-01).

 

Great!, I ordered yesterday the 65mm bolts to HE, should receive them in a few days. Thanks a lot for the explanation.
