Lancia Beta Forum

Good Morning to you all.

I was wondering if anyone has fitted the below wheels on a Beta
I am asking as I do not know the Offset.

These wheels are off the Nuovo Delta, 4 stud 98 PCD. There should be people on the LMC forum that own one of these cars so they should be able to tell you or you could try asking the seller to tell you what the ET number is ( this should be cast on inside of the alloy )

Hi, I have a set of speedlines , but not on a beta , there are a whole series of numbers and codes on the back , but nothing that indicates  what the offset is ! however on the front there are 2 markings , 61/2 x 15H2 and C-45 .
45 is possibly the offset , but I cant be sure

see below

Here you go.... it's actually fairly simple to do yourself.

Many thanks to you all. I know how to check the offset.
the problem is that the wheels are almost 600 kilometers far away!
The seller has no Idea how to check it, so i do not trust him.

My Trevi used to have Delta wheels fitted before I got it

The Delta wheels were then changed to standard Beta wheels

Looking at the two photos above (especially the rear wheels) the offset of the two types of wheels looks very similar so I'd say as a guess that the Speedline Delta wheels should fit a Beta.

Hi,  My speedlines are going on a 16v integrale but not fitted as yet , I have measured them as per MattnoVat's sketch , it works out as 45mm , so it would seem that the front marking of c-45 is the offset !!

Maybe they are not right for a Beta then. Beta wheels have a 34mm offset. Certainly the CD51 Cromodoras do as fitted to the early Series 1 Berlina ES. Then again the Speedlines are 6.5J while Beta wheels are 5.5J? So with the extra inch in width you'll need about 12mm extra offset so 34+12=46 which is very close to 45 so I'll go back to guessing they'll fit.

You can reduce the offset of a wheel by using spacers. I have the CD51s fitted to my Fiat 131 with 8mm spacers making them effectively ET26 which is what the Fiat needs.

The delta wheels on Thotos's Trevi are off an HF Turbo, not an Integrale.

I've seen those speedlines fitted to a 16v Grale before.

Sort of a poor man's TH2

Basically a 4 stud version of Evo wheels

It seems that 45mm is correct and no spacers can be attached.  :(
Many thanks to you all.

I removed the Cromodora CD-238 'HF Turbo' wheels because the offset was too deep.  Take another look at the rear arches.  The ET is quite different to the standard CD-160

very handy little website that I came across
