I can't seem to find a set of +30 A+ 1275 main bearings anywhere. Minispares sell the pre A plus version but not A+. Is it just a case of having to use pre A + bearings and file in new location tab grooves?

If this is for the 16v T i'd avoid the grooved bottom bearing.

I've given up searching for the plain/groove variety in -.030 If you find a supplier I would be interested too. On 7th Oct, 2010 5haneJ said:

Yep it's for the 16v engine. Seems odd +30 is available for all other bearings? https://www.facebook.com/pages/Fusion-Fabri..._homepage_panel

WhAt do you see the disadvantage being with the grooved bottom bearing? The only disadvantage I can see is less surface area to spread the load on, but then with the extra groove surely you're getting more oil around the bearing and better flow to the big ends?

Word on the street is that the +0.030" plain/groove bearings don't exist. None of the manufacturers stock them, AE, Glyco, ACL. They do however supply, so I am led to believe, +0.040" On 26th Oct, 2004 TurboDave16v said:

Well if 40's give one more stab at the crank and come in the correct size then good. I may have found a source too now! On 7th Oct, 2010 5haneJ said:

Sorry +40's. If they are of interest I can ask if they are definitely the correct variety. On 7th Oct, 2010 5haneJ said:

Keep us updated about how the groove/groove fair and how they look on strip down. should be interesting. On 7th Oct, 2010 5haneJ said:
