BMW 1 系列 (E8x) 以及 3 系列 (E9x) 車款的前軸採用雙節點彈簧柱麥花臣懸掛系統結構、這個雙接點彈簧柱結構扮演非常重要的角色，當做任何轉向運動時他同時控制著 caster, camber gain, toe, bump steer, roll center 等多種幾何角度同步補償，也可以說是前軸機械抓地力的核心來源。
而原廠在這兩隻控制臂上搭配了較軟的橡膠襯套，當車輛進行稍微激烈的動態運動下橡膠鐵套會因為壓縮型變產生不可預期的幾何角度偏移，我們為此製作了搭配高品質魚眼以及快速調節機構的高強度鋁合金上下控制臂，以原廠零件的預設角度為前提來提升懸掛節點結構鋼性。
控制臂採用優異的材質可以確保整體懸掛鋼性同步提昇，避免只單獨靠下橫臂做 camber 設置時造成 Thrust Arm 偏擺而讓橡膠鐵套預載扭曲加速損壞，也避免了結構鋼性產生差異而將大部分的型變應力單獨集中在上控制臂，全可調架構可以讓你在原廠設計的幾何比例前提下做更大幅度的特殊需求設置。
控制臂本體使用高規格 6065 Billet 鋁合金材質，數控 CNC 銑削成形，兩側則配置了鉻鉬合金鍛壓 Endura Series 高階賽車魚眼以及相關的高強度緊固件。
我們所有產品採用的 Endura Series 賽車魚眼由鉻鉬合金一體鍛壓成形，不透過額外的固定殼固定鋼心，而是直接將 51200 軸承鋼心透過特殊高壓注射製程將自潤滑的複合 PTFE/Nylon LINER 注塑成形包覆。這種單件鍛壓殼體擁有強大的抗屈服能力以及抗磨損能力，可以提供魚眼優異的支撐性能防止受力產生間隙，表面加鍍了硬鉻防止生鏽以及氧化的狀況發生，適用於極端的使用環境。
- 成套販售，套件包含 (Thrust Arm*2, Wishbone*2)
- 採用 6065 Billet 鋁合金數控 CNC 銑削
- FLURO Endura Series 魚眼
- 快速的調節機構
- 可靠的緊固結構
- 搭配可調懸吊上座可以進行 15-20mm 的輪距設定或是更大幅度的特殊定位角度需求設置
建議額外選購
- 單向 (Camber) 可調魚眼上座 (E81 E82 E87 E88 / E90 E91 E92 E93)
- 3D 全向 (Camber, Caster) 可調魚眼上座 (E81 E82 E87 E88 / E90 E91 E92 E93)
注意事項：
- *** 不適用於 xDrive 以及 AWD 車款 ***
- 由於性能取向的可調結構可能會改變控制臂總長，原始大燈水平感知器固定座將不再可用 (可依照需求另外進行固定孔位加工安裝)
- 原廠設計的前雙節點彈簧柱系統中控制臂呈現的虛擬交會點為特殊幾何結構，用以同時控制動態 Caster 角度變化以及 Camber 補償。任何變動控制臂長度需由專業技師調教，切勿任意將兩隻控制臂做不合比例的長度更動。
- 雙節點彈簧柱結構軸動態幾何角度補償非常複雜，我們建議在第一次安裝時將上下控制臂依照原廠控制臂長度作為標準，再依照需求調整，調整時請保持上下控制臂等比例長度更動，如需特殊調教或是技術支援請洽客服人員諮詢。
- 有限生產，接單訂製，訂購後可能需要等待 2-8 週 (依照訂單順序)

I like it. Work pretty will.
Sedra Echelon –
For the manipulative enthusiast, this is definitely something to invest in.
Lauri Ruonala –
As a buyer’s experience sharing, the workmanship and quality of the product are very good, the ball joint is also very tight, the installation and adjustment are very easy, the only disadvantage is that there is no mounting hole for the level sensor. It can be completed with small modifications.

Our team has ordered 8 sets this year, and so far none of the sets have been damaged during the whole year of the race. We are planning to order spare parts for next year’s addition, and are very impressed with this cost-effective product.
Luca Depalmas –
A very rare complete set of racing kits, most brands can only find the lower control arm, the overall workmanship is very good, the installation is easy to adjust and it survives five intense track days without any problems.
Hugo –
Hi, I am very interested in this kit, but one thing I would like to know is that BMW mounts the regulating link for the headlight level sensor on the lower control arm, and does your kit take that into consideration when designing and can accommodate the regulating link bracket?
TAG Engineering & JNK Motorsport –
Hi
thank for your contact!!
Because this parts design on performance and race, and length of the control arm can be adjusted, the fixed position of the level sensor cannot be completely fixed. You can process the installation keyhole after adjustment. The kit itself is not designed for the fixed position of the level sensor
Best Regards

Hello there
Do you have any dealer on the UK?
We have 4 teams of different races. Almost all vehicles that use BMW.
We are interested in becoming a partner with you. How can I get in touch?
Best Regards, FrankD.P

認真推薦！本來從美國買另外一間的零件.. 用沒多久內側的魚眼就壞了.. 向他們回報說是正常不予以保固= = 而且他們只有下控制臂.. 沒有上控制臂. 起先也一直猶豫一個台灣的品牌品質能有多好. 但是觀察了好一陣子發現 TAG 的專業程度並不比歐美品牌差於是就訂了一組，雖然等待時間有點長但是收到產品後真的是挺驚艷的. 目前使用也沒任何問題. 大鵬彎認真跑過幾場也都安然無恙. 重點是價格在國際上算是非常合理. 看來台灣也是有專業技術的店家跟品牌.

感謝您的推薦以及回報：）
KK Racing –
Finished the installation yesterday, the quality of your parts is really excellent. More cost-effective than other brands with higher prices.
TAG Engineering & JNK Motorsport –
Yes, this true. thanks man.
DZ Racing Team –
The quality of this product is very good, we have installed it on 5 race cars.
TAG Engineering & JNK Motorsport –
good to hear your reply. yes, we have provide the parts for a lot race team. we sure the quality and performance is pretty well. Thanks man! if you can . please share more photo for your race car : )

我在美國的車廠朋友一致推薦你們的東西.. 這東西你們還沒有出貨到美國的經銷吧？問他們他們說沒有進這組.. 我翻了一下全球只有你們有在做整套的.. 一般都只有下面那隻.. 看來我的 1M 又有毒物可以跟他們炫耀了..
TAG Engineering & JNK Motorsport –
您好！這個零件目前屬於接單製作的，我們美國的經銷商應該已經可以提供訂購了：）
