Hi All,

    Hopefully a simple questions for the informed masses - Has anyone had any experience with the rear diffuser from T4CS - I'm really interested in the fact it extends under the engine with an under tray, and in general looks well thought out. Does the diffuser help (increase grip and/or reduce rear lift), does it cause any heat issues and is the company still going? If nothing else it should keep the engine clean  ;D

thanks

No experience of that product but he does excellent work.

I am not sure he is still making stuff though.

I would give him a ring and see if he is. He will be able to answer your questions about it if he is still doing them.

He has been out of the country for ages. Family problems. Has been promising me an exhaust for over a year. You will have little chance of getting what you want

I have one I haven't fitted but had cuts for dual exhausts. It's nice and does seem to have good ventilation. Would sell if you're interested as it just won't work on the streets of Edinburgh!

You just need to learn to drive a bit better, nothing wrong with Edinburgh roads (if you find one open)   8)
