For those who have filled their mounts in their sw20 (or any other car really) with polyurethane, what stuff did you use and where did you get it?

In the States people seem to just use 3m windo-weld which is about shore a60, anything of that hardness or so would be great.

Not super keen on the super tough shore a80+ flexane as I think it would kill daily-ability, this is really just a way to make the dodgy mounts less jumpy.

Cheers

What are the various Sikaflex products rated to?
 
Found this comparing Skiaflex and Bostic products...

Would Sikaflex 255 Extra+ (windscreen adhesive - Shore A55) or Sikaflex 227 (fast automotive sealant - Shore A45) be suitable?

Cheers for the shoutout on sikaflex, I think I might go the middle ground and do Sikaflex 252! I've got some spare mounts at home so I'll update once they cure at home. Thanks for that!

There are proper mount inserts (kirasaurus or something like that) worth the money in my opinion, I bought from the USA.

I have had a set for years and love them, engine is firm without added vibration, makes you feel very connected to the drivetrain

I think Robk just got a set for his MR2 and I think was impressed with them.

i use sika flex 255 in my mounts.  last for years.

Did this on my AW11 and it lasted about 12 months with some track days and the mounts started to let go again, so YMMV. Recasting them in a harder durometer polyurethane is a better long term solution, IMHO.

Thats the stuff to use if you want to remake your engine mounts. I did this and it made 3 engine mounts. And there was a bit left over.
I just did the back ones of 3 cars. It helped eliminate a lot of the rock you get in your aw11 or aw11 supercharged or turbo starlet.

I used Sikaflex 252 for my engine mount, works beautifully. It is difficult to get out of the tube though I reccomend heating it up before you do it.
