I suggest you to relay on either "cultural factors" or DNA genealogy. They are not connected to each other in this particular case. As I have noticed here, 18 mutations between two 67-marker haplotypes cannot possibly be explained by a "split about 2850 years ago". Do the math. Who is "rather closely related" and to which "Type" is irrelevant here.
We have two facts here. One, that the Jewish R1a1 clade has a deep history. It split from the "mainstream" R1a1 which happened to be in the central Eurasia around 5000 years ago. 18 mutations in 67-marker ancestral haplotypes is the largest distance between any two R1a1 ancestral haplotypes in Europe. For example, the ancestral DYS388=10 haplotype is only 12 mutations away from the Russian Plain ancestral haplotype (including two mutations in DYS388). The Western Slavic (M458) base haplotype is 13 mutations away. The Central European base haplotype is 16 mutations away. The Old Scandinavian base haplotype is 4 mutations away. The Jewish base haplotype is 18 mutations away. It is the most distant one from the Russian Plain base haplotype. Clearly, it was not a "Jewish" when it was carried away. Another fact is that the R1a1 haplotype got into the Jewish community relatively recently, 1100+/-150 years ago. Where did it happen, nobody knows. Preconceived knowledge does not work here. It is not science.

> No, R1a1 haplotypes do not say anything about the Khazar hypothesis. They just tell us that the Jewish R1a1 ancestral hyplotype split from the Russian Plain R1a1 ancestral haplotype around 5100 years before present, and a R1a1 common ancestor of the present-day R1a1 Jews lived 1100+/-150 years before present.
