FEATURES:
Valve Spring Retainers are an indispensable part for any high powered, high speed engine. The combination of high lift camshafts and these oversized valves will greatly increase the flow rate for fuel mixture to enter the combustion chamber. When upgrading the Valves to cope with the new high lift camshafts it is also a requirement to upgrade the Valve Springs to suit the new setup. High engine speeds and the dynamic movement of the valve trains mass can cause unwanted stress loads. This can cause abnormal movements such as a Valve jump or Valve bounce which can cause engine failure. The Tomei Retainers are made from Titanium alloy for added weight reduction whilst maintaining the high strength properties and precision required for the nature of its use. This will help keeping the Valves under control and secure the Valve in place during extreme race conditions.
Compatibility is from maker for JDM cars only. We don't guarantee fitment. Always do your own research before purchase.

Installed these along with the front rigid collars on my Scion iM. What a huge difference these actually make. I expected something very minor but noticeable as Spoon's demonstrations didn't give a great idea to it, but these truly changed how the car feels when hitting some minor bumps in the road. You do get some feeling of pseudo-polyurethane bushings as the car does try to bounce around since the subframe is stiffened up a bit when road driving, but on track it really gives you a better feeling of connection to the asphalt. Overall fantastic.

Installed these on my Scion iM and with some very minor trimming they fit well and WOW the amount of extra play room that you get within the engine bay is quite surprising without the old fashioned hood support rod in your way. The price? In my opinion it's high for what you get, but the added convenience factor does help almost wash out the hit to your wallet. Overall well made and worthwhile if you're constantly tinkering under the hood.

LOVE this countersunk knob from ARVOU. Great weight, pleasing form and feel. With the knob being countersunk, you eliminate the need for short shifter, as this compliments the stock shifter well.

Impressed with the quality of ARVOU goods, this installs easily and looks great. No modifications needed to install, just remove bumper, bolt in, reattach bumper.
