rutts Posted April 3, 2011 Share Posted April 3, 2011 red for 3.44 yellow for 3.67 can also depend on wheel/tyre size. Quote Link to comment Share on other sites More sharing options...
surfup* Posted April 12, 2021 Share Posted April 12, 2021 If I have 3.67 in the diff and 205 60 13 section tyres would yellow be the right one? Where can I get one Thanks appreciated Quote Link to comment Share on other sites More sharing options...

Mickfrad Posted April 12, 2021 Share Posted April 12, 2021 I think it is but someone may be able to confirm this for you, or send a message to edelschmiede. They are very helpful and knowledgable. Quote Link to comment Share on other sites More sharing options...

surfup* Posted April 15, 2021 Share Posted April 15, 2021 Well they never come back to me, any advice on which color I should go for with 13" rims I do appreciate it Quote Link to comment Share on other sites More sharing options...
Mickfrad Posted April 15, 2021 Share Posted April 15, 2021 (edited) Plenty of speedo drive calculators online using tyre sizes final drive etc. But you need to know the drive gear size for your box which someone may be able to help with as I don’t know. This YouTube clip may help to explain things a little better. Links to a couple of the calculators. which may help. http://www.gtsparkplugs.com/SpeedoGearCalc.html https://transmissioncenter.net/shop/speedometer-gear-calculator/ Edited April 15, 2021 by Mickfrad Quote Link to comment Share on other sites More sharing options...
cam.in.head Posted April 16, 2021 Share Posted April 16, 2021 looking at a wheel diameter calculator the standard 165/80/13 and 185/70/13 .your size of 205/60/13 comes in just a tad lower so a yellow driven gear should work ok.better to be on the lower side than above .speed camera wise ! 2 Quote Link to comment Share on other sites More sharing options...

surfup* Posted April 18, 2021 Share Posted April 18, 2021 Is the 1.8 OHC gearbox a 265 or a 240? I want to purchase the correct drive. On the website it states CIH for both gearboxs Thanks Quote Link to comment Share on other sites More sharing options...
H-400 Posted April 18, 2021 Share Posted April 18, 2021 1.8 has got the 240, but the speedo drive from Edelschmiede fits on both. Quote Link to comment Share on other sites More sharing options...

That's really helpful mate as I need to change mine in the 265 box👍 Quote Link to comment Share on other sites More sharing options...
H-400 Posted April 19, 2021 Share Posted April 19, 2021 As promised: Not the sharpest pic but you can see the speedo drive is identical as the 240, the old 4 speed and the automatic. 1 1 Quote Link to comment Share on other sites More sharing options...

rutts Posted April 20, 2021 Share Posted April 20, 2021 I have the blue one fitted in my getrag 265. 1 Quote Link to comment Share on other sites More sharing options...
H-400 Posted April 20, 2021 Share Posted April 20, 2021 My rear axle is (original) an 3.18 so thats maybe why. When I drive 200km/h the speed on my GPS is 202km/h chrono. So my speedometer is rather accurate. Remember this while I was chasing a Shelby Cobra on the German highway to the Nürburgring. We exchanged thumbs up while I pushed harder and passed him. 3 Quote Link to comment Share on other sites More sharing options...
