    Valvetronic Exhaust

    This is purely an FYI/observation and not a bash or anything against those guys, take it for what it is. Their header design places the primary o2 sensor in a single runner vs at the collection/collector point of the three runners which in my book and others is a no-no. When this is done the...

    GRP Intake Shootout Dyno Testing!

    I do honestly think the Eventuri and our intake will show a bit more power if we put some drive time on them, would it be 20hp as claimed by them? Based on our results today I dont think so, more like 10-15. FWIW our intake kit on the Evora's is a pretty consistent 10hp bump over stock based...

    GRP Intake Shootout Dyno Testing!

    Scheduled in for the 16th but hoping they have a cancellation sooner. The weather looks like it will be similar here for the next couple weeks so results shouldnt be skewed much if any by that.

    GRP Intake Shootout Dyno Testing!

    This morning we took our shop car to the dyno and did a "shootout" of sorts for various intake and filter options. Ive made as detailed account of everything as I can below but feel free to ask any questions! Basic Info - Car is Un-tuned, stock ecu. Was around 70 degrees when we started...

    Anyone developing a gloss black body kit?

    Our splitters, skirts and spoilers will all be available in gloss black.

    Steering Wheel Press-Type Buttons Now Available from GRP!

    I can probably do that, we will swap a set in the shop car and try to capture a video of the process. We do have written instructions on our website under the custom wheel page that shows how to do it as well.

    Does anyone have GRPs Spacers?

    12mm kits should be ready in about 2-3 weeks. They will be available in an anodized black like the current 10mm ones are done in.

    Does anyone have GRPs Spacers?

    With 5/6mm spacers you have enough of the factory hub protruding that you don’t have to worry about centering.

    Steering Wheel Press-Type Buttons Now Available from GRP!

    It does need to be unplugged but it’s a basic flat electrical plug that sits behind the airbag inside the wheel. Easy peasy 👍🏻

    Does anyone have GRPs Spacers?

    As @Porter mentioned with 10mm spacers you do lose the "spigot" for hanging the wheel on during install so some extra care has to be taken when tightening things up. With that said we have found that is not something a lot of guys have the patience for so we are going to start offering 12mm...

    Haha, not that sort of a pop out! Yeah, we should have these readily available and in stock once we get our first shipment.

    Steering Wheel Press-Type Buttons Now Available from GRP!

    The airbag needs to be removed to access the screws to swap the switches. Its a super easy 2 minute job to remove the airbag once the battery is disconnected --just two spring clips presses and it pops right out.

    Steering Wheel Press-Type Buttons Now Available from GRP!

    You need to disconnect the battery first, then once that is done you can unplug the airbag and not have any worries about the airbag light coming on. Only way that can happen is if its disconnected while the battery is connected.

    Steering Wheel Press-Type Buttons Now Available from GRP!

    I could have specified, sorry. You just need to remove the airbag and then you will have access to two small torx screws that hold each button ably in place. Once those are removed the buttons will pull outward, unplug and you can swap them out.

    These are like the current buttons with a satin type finished button surface and a glossy black surround trim.

    A lot of you were annoyed with the touch sensitive type buttons on the steering wheels from the factory and for good reason, those things are too sensitive! We now have the press type buttons available to order on our site. (Ready to ship out around Aug. 5th) These are brand new...

    GRP Forged Monoblock Wheels Now Available!

    We have to rely on customers sending in pictures which doesnt always happen so they are limited right now but will grow steadily. I will ask the owner of that car if he has more to share.

    GRP Forged Monoblock Wheels Now Available!

    Depending on tire choice it works out to about $5575 for a complete setup, mount/balanced, shipped and ready to put on the car.

    In 19" front and rear? Those would come in right about 19.5-20lbs for the front and 20.5-21lbs for the rear. The 19" listed weight on our site is from a set of 18/19 we did for our 3-Eleven.

    Full exhaust o2 problem

    This has been a long time "safety" thing that Lotus does in the tuning of the ECU. In the Elise,Exige and Evora there is a soft limiter built in until the engine is up to temp, same goes for the Emira. It will limit power/timing until the engine is up to temp.

    GRP Titanium Exhaust going on the Stradman's Emira

    We will be doing a baseline dyno next week on the shop car during our intake shootout. When we go back again we will do another one with the titanium exhaust installed. We dont have that scheduled yet but it will hopefully be soon!

    Eventuri development

    Doing all of the variations you mentioned on the dyno wont really be feasible in one trip since the exhaust cant be swapped on the dyno like the intake/filters can. Next week I think we will do our runs with totally stock exhaust, drop in filters and both intakes. Then schedule another...

    The factory intake is sealed up nearly the same way but has drain holes as well so its a non issue imo.

    GRP Titanium Exhaust going on the Stradman's Emira

    There is definitely still the overrun crackle and burble there but maybe not as much at higher rpms like @Nova mentioned.

    Has anyone installed the lowering kit from GRP ??

    Moving the lower spring perch position down in no way would require going to a higher spring rate. Lotus themselves did this same thing but with circlip positioning between the S1, S2 and GT Evora's.

    Eventuri development

    Dyno day is scheduled for the 31st. We have the annual Hot August Nights car event coming up here in town so all of the performance shops are slammed with work right now getting cars ready which put us way out on scheduling.

    Has anyone installed the lowering kit from GRP ??

    Not sure I follow on this, you dont change spring rates anytime you adjust a coilover do you?

    GRP Emira Decat Pipes Now Available!

    We only offer the decat pipes in stainless currently. Aside from weight I dont really see any benefit of titanium at the decat pipe. Regardless though you would have two different materials, either at the muffler intlet or at the decat pipe to midpipe flange, it wont cause any issues either way.

    GRP Emira Decat Pipes Now Available!

    Just brand really. They are both a bolt in straight pipe that achieves the same thing. Millteks are made in the UK while ours are made here in Reno NV.

    📓 Journals Adding Lightness

    Forgot to ask @Eagle7 did they not log AFR's? We will when we do our runs to see the effect on those from each intake setup. @LuckysDad Filter swap isnt too bad, there are three torx screws that have to be removed that are the biggest pain of the whole swap.
